[#315] Which one of the following is not correctly matched in the term of Mammal/bird and Chromosome number (2n)?
Correct Answer

(D) Ass ⇔ 64

Explanation

Solution: A. The chromosome number (2n) in Cattle, goats is 60. The present day cattle and goat possess the same diploid chromosome number (2n = 60) and structurally similar autosomes, except that a small subcentromeric portion of cattle chromosome nine has been translocated to goat chromosome 14. B. The chromosome number (2n) in Buffalo is 50. The river buffalo karyotype (2n = 50) has five biarmed pairs (submetacentric chromosomes). The remaining chromosomes are acrocentric, including both the X, being the largest acrocentric chromosome, and Y, the latter being one of the smallest acrocentric chromosomes. C. The chromosome number (2n) in Fowl is 78. The karyotype of chicken, Gallus domesticus consists of 2n = 78 chromosomes. However, 12 chromosomes, or 6 pairs are called microchromosomes and the remaining 66, or 33 pairs of chromosomes are called microchromosomes. D. The chromosome number (2n) in Ass is 64. It is not correctly matched.
