NEET BIOLOGY

Detailed explanation-1: -In a horse cell, this would mean the parent cell starting meiosis had 64 chromosomes. Then, this cell divides once during meiosis one, producing two daughter cells that each have 32 chromosomes. Then, those daughter cells divide again during meiosis II to produce four cells that each have 16 chromosomes.

Detailed explanation-2: -The diploid number of chromosomes in horses (Equus ferus) is 64 and the diploid number in donkeys (Equus africanus) is 62. When a male donkey and a female horse are mated, the result is a mule which has 63 chromosomes.

Detailed explanation-3: -Horse diploid cells contain 64 chromosomes (2n=64).

Detailed explanation-4: -The diploid number of chromosomes found was: horse sixty-four, donkey sixty-two, mule sixty-three, hinny sixty-three. In addition to the numerical differences between horse and donkey, there exist structural differences which are most noticeable in greater numbers of metacentric chromosomes in the donkey.
