GEN Lecture 5

Question 1

Mendels first law:

Answer 1

Two alleles segregate during gamete production e.g. the sperm and egg each carry one allele. Diploid state is restored by fusion of gametes.

Question 2

Mendel’s second law:

Answer 2

Each allele pair assorts independently of other allele pairs during gamete formation. The alleles of unlinked genes assort independently.

Question 3

Autosomes:

Answer 3

Non-reproductive chromosomes (22 pairs in humans)

Question 4

Recombination of unlinked genes:

Answer 4

occurs by independent assortment

Question 5

Recombination of linked genes:

Answer 5

Occurs by crossing over during meiosis. Linked genes do not assort independently.
