Q
Define ‘Haplotype’.
A
A group of genes inherited together from a single parent.
Can also refer to inheritance of SNP cluster.
6
Q
State ‘Mendel’s 2nd law’.
A
Alleles of different genes assort independently. (recombinant phenotypes appear as consequence)
7
Q
State ‘Mendel’s 1st law’.
A
Alleles of a gene will segregate.
8
Q
How do you calculate the recombination frequency?
A
RF = R / (R+P) R = recombinants no. P = parental type offspring no.
