Which of the following statements correctly describes what happens to a chromosome after a nonreciprocal translocation occurs? A chromosome transfers a fragment but receives none in return.
Which of the following statements correctly describes the meaning of the chromosome theory of inheritance as expressed in the early 20th century?
Which of the following statements describes the chromosome theory of inheritance as expressed in the early twentieth century? Mendelian genes are at specific loci on the chromosome and in turn segregate during meiosis.

Terms in this set (23) Which of the following statements explains the observation that closely linked genes are typically inherited together? The genes are located close together on the same chromosome.
Which of the following statements correctly describes the reason that closely linked genes are typically inherited together group of answer choices?
Which of the following statements correctly describes the reason that closely linked genes are typically inherited together? They are located close together on the same chromosome.
How does the recombination of linked genes contribute to natural selection?
How does the recombination of linked genes contribute to natural selection? It maintains genetic variability in a species.
Which of the following results in a situation in which the chromosome number is either 2n 1 or 2n − 1?
Which of the following results in a situation in which the chromosome number is either 2n+1 or 2n-1 ? An aneuploid individual has either too many or too few chromosomes, usually as a result of nondisjunction.
Which of the following events causes recombination between linked genes to occur quizlet?
Which of the following events causes recombination between linked genes to occur? Crossovers between these genes result in chromosomal exchange.
Why does recombination between linked genes occur?
Recombination can occur between any two genes on a chromosome, the amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency.
Which of the following statements correctly describes the recombination frequency between two genes?
So, the correct answer is 'The closer together two genes are on a chromosome, the smaller their crossover percentage'.
What does genetic recombination do?
Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
How does genetic recombination increase genetic variation?
Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.
Which of the following events causes recombination between linked genes to occur group of answer choices?
Which of the following events causes recombination between linked genes to occur? Crossovers between these genes result in chromosomal exchange.
Which of the following statements correctly describes the characteristics of recombinant chromosomes?
Which of the following statements correctly describes the characteristics of recombinant chromosomes? At least one to three times per chromosome pair, they carry genes from two different parents. In the life cycle of fungi and some protists, which of the following processes leads to the formation of gametes?
Why does recombination occur between linked genes?
Recombination can occur between any two genes on a chromosome, the amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency.
How does recombination of linked genes contribute to natural selection?
How does the recombination of linked genes contribute to natural selection? It maintains genetic variability in a species.
What is the recombination frequency between linked genes?
Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
How is linkage correlated with recombination?
In linkage, two or more genes linked together are always inherited together in the same combination for more than two generations, whereas in recombination the genetic material is exchanged between different organisms which leads to the production of offsprings with the combination of traits.
Which of the following statements best describes the process of crossing over genetic recombination?
Which statement best describes the process of crossing-over? It takes place between homologous chromosomes and results in new gene combinations.
How do you find the recombination frequency between two genes?
The # of recombinant offspring / total # of offspring x 100% = recombination frequency.
What causes recombination of genes?
During the alignment, the arms of the chromosomes can overlap and temporarily fuse, causing a crossover. Crossovers result in recombination and the exchange of genetic material between the maternal and paternal chromosomes. As a result, offspring can have different combinations of genes than their parents.
What causes recombination to occur?
Recombination occurs randomly in nature as a normal event of meiosis and is enhanced by the phenomenon of crossing over, in which gene sequences called linkage groups are disrupted, resulting in an exchange of segments between paired chromosomes that are undergoing separation.
How does recombination occur?
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
What causes genetic recombination?
During the alignment, the arms of the chromosomes can overlap and temporarily fuse, causing a crossover. Crossovers result in recombination and the exchange of genetic material between the maternal and paternal chromosomes. As a result, offspring can have different combinations of genes than their parents.
How the linked genes segregate together while crossing over produces recombination between them?
1: Linked genes can be separated by recombination: The process of crossover, or recombination, occurs when two homologous chromosomes align during meiosis and exchange a segment of genetic material. Here, the alleles for gene C were exchanged. The result is two recombinant and two non-recombinant chromosomes.
Which statement best describes the process of crossing over?
Which statement best describes the process of crossing-over? It takes place between homologous chromosomes and results in new gene combinations.
What is linkage and recombination?
In linkage, two or more genes linked together are always inherited together in the same combination for more than two generations, whereas in recombination the genetic material is exchanged between different organisms which leads to the production of offsprings with the combination of traits.
Which among the following best describes recombination or crossing over of chromosomes?
The correct answer to the above question is: B. Chromatids of homologous chromosomes exchange corresponding segments.
How do you determine linkage and recombination frequency?
We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.
What is the process of recombination?
Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
Which phase does recombination occur in?
Prophase of Meiosis I Recombination Occurs During the Prolonged Prophase of Meiosis I. Prophase I is the longest and arguably most important segment of meiosis, because recombination occurs during this interval. For many years, cytologists have divided prophase I into multiple segments, based upon the appearance of the meiotic chromosomes.
