How many chromosomes do apples have?
17 chromosomes Key basic discoveries reported by Velasco and co-authors1 were: (1) the 17 chromosomes of the apple genome are monophyletically derived from a relatively recent genome-wide duplication of an ancestral 9-chromosome Rosaceae ancestor, giving a particular pattern of chromosomal homologies; (2) the gene pool of cultivated …
What happens when you have 47 chromosomes?
Trisomy ('three bodies') means the affected person has three copies of one of the chromosomes instead of two. This means they have 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.

How many chromosomes does a dog have?
78 chromosomes Each chromosome contains hundreds or thousands of different genes. Chromosomes are found in pairs within the cell. Each cell contains two separate copies of each gene (alleles). While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs).
How many chromosomes do spiders have?
Diploid chromosome numbers of spiders range from 7 (Suzuki 1954) to 128 (Král et al. 2013).
How many chromosomes does a snake have?
36 chromosomes The vast majority of snakes have diploid numbers (2n) of 36 chromosomes, containing 16 macrochromosomes and 20 microchromosomes (19,20). However, variations involving macro and micro karyotypic structure and a diploid number have also been reported in different families across snake lineages (21,22,23,24,25).
What animal has 60 chromosomes?
The goat (Capra hircus) also has a chromosome number of 60 (Sokolov, 1930; Shiwago, 1931). The chromosomes of the goat were recently studied by Basrur and Coubrough (1964), who found all chromosomes to be acrocentric.
What is the chromosome number of mango?
40 chromosomes Mango has a total of 40 chromosomes, which suggests a haploid number of chromosomes as 20 and similarly 20 linkage groups.
How many chromosomes do strawberry have?
The strawberry of commerce is octoploid (2n = 8× = 56; seven chromosome sets and eight chromosomes per set, 56 total), meaning that each cell contains remnants of four separate ancestral diploid subgenomes that underlie strawberry's form and function.
CAN XXY be a girl?
Generally, individuals possessing 47, XXY karyotype have male phenotype. However, in the present case in spite of the presence of Y chromosome and the normal SRY, SOX9, and ZFY genes, the individual has a female phenotype.
Is XXY male or female?
Usually, a female baby has 2 X chromosomes (XX) and a male has 1 X and 1 Y (XY). But in Klinefelter syndrome, a boy is born with an extra copy of the X chromosome (XXY). The X chromosome is not a "female" chromosome and is present in everyone. The presence of a Y chromosome denotes male sex.
Can a human have 50 chromosomes?
Normal human cells usually have 23 pairs of chromosomes; however, cancer cells can have 50 or more chromosomes.

How many chromosomes does a mango have?
40 chromosomes Mango has a total of 40 chromosomes, which suggests a haploid number of chromosomes as 20 and similarly 20 linkage groups. The haploid genome size is estimated at ~439 Mb (Arumuganathan and Earle, 1991).
Is there a YY gender?
Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes. Identifying genes on each chromosome is an active area of genetic research.
Is XO male or female?
Males Males only have one X chromosome (X0), while females have two (XX). The zero (sometimes, the letter O) signifies the lack of a second X. Maternal gametes always contain an X chromosome, so the sex of the animals' offspring depends on whether a sex chromosome is present in the male gamete.
Do humans have 47 chromosomes?
Summary. Humans have 23 pairs of chromosomes. A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.
How many sexes are there?
two sexes Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).
