Answer 2

Answer:

i)In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

ii)While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs). The exception to this rule is sperm cells and egg cells.
