GEN Lecture 5 Flashcards
1
Q
Mendels first law:
A
Two alleles segregate during gamete production e.g. the sperm and egg each carry one allele. Diploid state is restored by fusion of gametes.
2
Q
Mendel’s second law:
A
Each allele pair assorts independently of other allele pairs during gamete formation. The alleles of unlinked genes assort independently.
3
Q
Autosomes:
A
Non-reproductive chromosomes (22 pairs in humans)
4
Q
Recombination of unlinked genes:
A
occurs by independent assortment
5
Q
Recombination of linked genes:
A
Occurs by crossing over during meiosis. Linked genes do not assort independently.
