The diagram represents a change that occurred in a pair of chromosomes during the formation of an egg cell.

Question

The alteration that occurred will most likely be passed on to every cell that develops from the egg cell. Why would this type of alteration result in offspring with combinations of traits that differ from those found in either parent?

a
It results in the formation of diploid gametes.
b
It changes the chromosome number of the body cells that develop from the egg cell.
c
It results in new combinations of genes on each chromosome.
d
It converts sex cells into body cells.

Answer 1

The correct answer is:

c It results in new combinations of genes on each chromosome.

This option explains that the alteration in the chromosomes can lead to genetic recombination, which creates different combinations of traits in the offspring compared to either parent. This is a key process in sexual reproduction that promotes genetic diversity.
