Label the structure indicated by lines (i), (ii), (iii) and (iv):

The members of a homologous pair of chromosomes:

(1) Are identical in size and appearance

(2) Contain identical genetic information

(3) Separate to opposite poles of the cell during mitosis

(4) Are found only in haploid cells

One difference between mitosis and meiosis I is that:

Chromosome number is reduced during meiosis because the process consists of:

Which of the following is false?

A reduction step during meiosis is important because:

(1) It returns the chromosome number to normal before fertilization

(2) There is a mechanism for this

(3) Only one copy of each chromosome is necessary

(4) Otherwise chromosome copies would double each fertilization
