AEST Animal Science Specialist Certification Practice Exam

The diploid number of chromosomes in cattle is indeed 60, which is not correctly represented by the selected answer of 30. It's important to understand that the diploid number refers to the total number of chromosomes present in a typical somatic cell, and in cattle, this includes two complete sets of chromosomes from each parent.

Cattle have 30 pairs of chromosomes, which totals 60 chromosomes. Each pair consists of one chromosome inherited from the mother and one from the father, thus forming a complete diploid set. The number is significant as it plays a crucial role in genetic studies, breeding practices, and understanding cattle genetics overall.

The other options mention significantly lower numbers, which do not reflect the actual chromosome count in cattle. Understanding the correct diploid number is vital for various practices in animal genetics and breeding programs.
