Question

a species of honeybee has 32 chromosomes in its body cells. during the reduction - division stage, the nucleus divides into 4 nuclei. how many chromosomes are contained in each nucleus?

Explanation:

Step1: Recall the concept of reduction - division (meiosis)

In meiosis, the chromosome number is halved.

Step2: Calculate the chromosome number after meiosis

The body cell has \(n = 32\) chromosomes. After meiosis (reduction - division), the chromosome number is \(\frac{n}{2}\). Then, when the nucleus divides into 4 nuclei (after meiosis II), each nucleus gets \(\frac{n}{2}\) chromosomes. Since \(n = 32\), \(\frac{32}{2}=16\)

Answer:

16
