Question
Chapter 9, Problem 6WIO
Summary Introduction
To explain:
From where do the members of each pair of chromosomes of the diploid cell comes.
Concept introduction:
The chromosomes are formed by the packing of the DNA (deoxyribonucleic acid) onto the protein molecules. Most of the sexually reproducing organisms are diploid that is they have two sets of chromosomes in a cell. Each set of the chromosomes has a similar chromosome number. The same chromosomes of the two sets are known as homologous pair.

What are the respective functions of the
separation of homologous chromosomes and
of the separation of identical chromatids
during meiosis?
How does anaphase I of meiosis differ from anaphase of mitosis? Does the number of chromatids per chromosome change in anaphase I? Does the number of sets of chromosomes per nucleus change in anaphase I?
If an organism has 15 pairs of homologous chromosomes, how many chromosomes will each daughter cell have after telophase of mitosis? In this same organism, how many chromosomes will each daughter cell have after telophase II of meiosis?
