Goats, cows, yaks, and bison have 60 chromosomes in their body cells. How many chromosomes would their sex cells have?
A
60
B
30
C
23
D
4
Explanation: 

Detailed explanation-1: -The bison’s sperm cells would have 30 chromosomes because the sperm cells are gametic cells which are haploid cells.

Detailed explanation-2: -For instance, karyotype of cattle is composed of 58 acrocentric autosomes and two subtelomeric sex chromosomes (2n = 60, XX or 2n = 60, XY) [11].

Detailed explanation-3: -Wood bison and plains bison possess a diploid number of 60 chromosomes. The 58 autosomes are all acrocentrics, the X chromosome is sub-metacentric, and the Y chromosome is a small acrocentric.

Detailed explanation-4: -A cow has 60 chromosomes in one of its somatic cells.

Detailed explanation-5: -What is the haploid chromosome number of cattle? The diploid number for cattle is 60 (2n=60). How many PAIRS of chromosomes do cattle have? The diploid number for cattle is 60 (2n=60).
