What is the probability of producing the genotype AaBbCc in the cross AaBbCc?
So, the correct answer is '1/8. '
How many types of gametes can be produced from genotype AaBbCc?
Explanation: A plant having genotype AABbCC will produce only two types of gametes, ABC and AbC.
What is the genotype of AaBbCc?
The plant having the genotype AaBbCc is a triploid plant. To calculate the total number of gametes that are produced by a particular genotype, a specific formula 2n is used, where n= number of heterogeneous alleles that are found in the genotype.
What proportion of the offsprings obtained from cross Aabbcc Aabbcc will be completely heterozygous for all genes segregated?
1/8 So the answer is '1/8'.
How many allele combinations are in AaBbCc?
Since each parent has four different combinations of alleles in the gametes, there are sixteen possible combinations for this cross.
When AaBbCc is crossed with AaBbCc then the ratio of hybrid for all the three genes is?
As seen from the above, the ratio of hybrid for all the three genes (AaBbCc) = 1/8.
How do you find the proportion of an offspring?
Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
What proportion of the offspring will have the following phenotype ab ab AB and AB?
Predicting the genotype of offspring Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
When AaBbCC is crossed with AaBbCC then the ratio of hybrid for all the three genes is?
As seen from the above, the ratio of hybrid for all the three genes (AaBbCc) = 1/8.
How many types of gametes can be produced by YyRr?
After fertilisation, the F1 heterozygote will be formed i.e YyRr (yellow and round). On selfing F1 we get two possible combinations i.e YR, Yr, yR, yr. Therefore four types of gametes are formed in the ratio of 1:1:1:1. Thus, the correct answer is option D.
How many offsprings will be formed by the mating between two parents having the genotype Aabbcc?
In the above question the parents genotype is given AABBcc $ times $ AaBbCc. The cross is made between them after the cross the three genes formed will be AaBbCc heterozygous regarding three genes….
| Parents | cc | Cc |
|---|---|---|
| c(Homozygous) | Cc(heterozygous) | |
| Offspring | cc | Cc |
What is genotypic ratio of trihybrid cross?
With three unlinked genes, each parent can produce 8 different types of gametes, which generates 64 possible genotypic combinations. The phenotypic ratio of the trihybrid cross is 27:9:9:9:3:3:3:1.
How do you find the genotype probability?
Using a similar Punnett square for the parents' fur texture alleles, the probability of getting an Cc genotype is also 1 / 2 1/2 1/2 . To get the overall probability of the BbCc genotype, we can simply multiply the two probabilities, giving an overall probability of 1 / 4 1/4 1/4 .
How do you calculate genotypes?
As more and more genes control a trait, a greater number of genotypes are possible. The formula that predicts the number of genotypes from the number of genes is 3 to the power n. (n is the number of genes.)
What is the probability that parents AaBb and AaBb will have offspring with genotype AaBb?
Answer and Explanation: The correct answer: The probability of an aabb offspring when AaBb x AaBb parents are crossed is b. 1/16 . See full answer below.
What is the probability that an individual will have a genotype of AaBb AaBb AaBb AaBb?
18.75% The genotypes are aaBB and aaBb. We add the probabilities for these genotypes together and have a probability of 18.75%.
How many gametes are formed from pea plant having genotype YYRR?
two different YR and yR are two different genotype gametes may be formed from this genotype.
How many types of gametes would be produced if the genotype of a parent is AaBb A 1 B 2 C 3 D 4?
There are four possible combinations of gametes for the AaBb parent.
How many allele combinations are in Aabbcc?
Since each parent has four different combinations of alleles in the gametes, there are sixteen possible combinations for this cross.
What will be the frequency of AaBbCc in Trihybrid test cross ratio?
According to the question, a perfect heterozygous cross will occur only when abc gamete from AaBbCc parent fertilises with ABC gamete from AABBCC parent. Thus, the frequency for this = 1/8X1 = 1/8.
What is genotype of trihybrid cross?
A cross between two individuals that are heterozygous for three different traits is called a trihybrid cross. Consider a cross of F2 generation between organisms with genotype AaBbCc. As shown in the figure the phenotypic ratio of a trihybrid cross in F2 generation will be 27:9:9:9:3:3:3:1.
What is the probability of YyRR from a cross of YyRR and YyRR?
50% From the cross worked out in the above Punnett square, we can see that the gametes from both parents combine to give rise to progeny with two characteristic genotypes, YyRR and yyRR. The chance for occurrence of each of these genotypes is 50%.
What is the formula of probability?
Formula to Calculate Probability The formula of the probability of an event is: Probability Formula. Or, P(A) = n(A)/n(S)
How do you do a Trihybrid cross?

How many genotypes are possible?
six different genotypes A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes?
Which two genotypes are the recombinant offspring a AABb & AABb B AABb & AABb C AABb & AABb D AABb & AABb?
Genotypic ratio = 1 AABb : 1 Aabb : 1 aaBb : 1 aabb. Correct answer is C.
How many genotypes will be produced in the cross AABB * AABB?
So, the correct answer is, '16. '
When AABB is crossed with AABB in F2 generation the ratio of AABB is?
Probability of AaBb in F2 generation= 4/16. Correct answer is D.
What is the genotype of YYRR?
Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color. yy is the homozygous dominant genotype (2 y alleles)….Mendelian genetics review.

How many types of gametes could be produced by a YYRR plant?
P generation: A yellow, round plant (YYRR) is crossed with a green, wrinkled plant (yyrr). Each parental generation can produce only one type of gamete, YR or yr.
