Mendel’s law of independent assortment only holds true for what?
Genes that are NOT carried close together on the same chromosome.
What ratio would you predict if the genes are closely linked during a cross?
Two types of progeny: parents genotypes in equal proportions.
Recombination frequency is proportional to what?
Distance between two loci.
During Meiosis I, what ensures that homologues are held together?
Multiple recombination events along the length of the chromosome.
Recombination frequency is always between what?
0-50%
If two loci are right next to each other what happens? (in terms of RF)
No crossing over = no recombinants = 0% RF.
If two loci on separate chromosomes what happens (in terms of RF)
50% recombinant + 50% parental = 50% RF.
