Question

Llamas have sexual reproduction. Some types of llamas have 74 chromosomes. That is how many chromosomes are in their somatic (body) cells. How many chromosomes would be found in their gametes?

Answer 1

Answer: 37 chromosomes.

Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.
