2
Q
Why do linked genes behave the way they do?
A
They are found on the same chromosome
They are physically joined together
3
Q
If genes are linked how can you get new combinations of alleles in gametes?
A
Genetic recombination
4
Q
What are the 2 mechanisms of genetic recombination in higher organisms?
A
Crossing over
Independent assortment
5
Q
What was Mendels second principle?
A
Independent assortment of alleles (of different genes)
i.e equal chance of obtaining all possible combinations of alleles from different genes in the gametes
