This type of malformation results from trisomies.
Typically, a chromosome contains hundreds to thousands of genes.
When a karyotype is taken, a chromosome typically has two chromatids.
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
There are 2n possible homologous chromosome alignments, where n is the number of homologous pairs of chromosomes.
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.

1 out of every 500 people are affected with Polydactyly, being most common in black males and least common in white females.
Polydactyly is associated with different mutations and is a congenital phyiscal anomoly found in humans, dogs and cats. causing them to develop too many fingers or toes.
Polydactyly is a genetic disorder which leads to one having six fingers or toes. This is also known as hexadactyly. It is caused by an autosomal dominant gene. ~ Poly = many dactly = fingers and toes. Polydactyly means more than the usual number of fingers and/or toes. Some cases can be genetic but most are not and there can be any number (not necessarily 6).
polydactyl means many fingers. It refers to people or creatures that have more fingers or toes then what they are suppose to have.
A chromosome is made up of many genes.
An organism with 5 pairs of chromosomes can produce a maximum of (2^n) different gametes, where (n) is the number of chromosome pairs. In this case, (n = 5), so the calculation is (2^5), which equals 32. Therefore, the organism can produce 32 different gametes through the processes of independent assortment and recombination during meiosis.
in a homologous chromosome there are two chromosomes ( a chromosome and a sister chromosome)
You can produce many different errors, here is an example: int main (void) { *(char *)main = 'A'; return 0; }
