Unformatted text preview: genes located on the same chromosome.
a) What are the F1 genotypes and phenotypes for the cross
hP/Hp x hp/hp
Genotypes & Phenotypes: hP/hP (bald pimpled); Hp/hp
(Hairy Clear) b) What would recombinant gametes look like?
HP, hp Frequency of Crossing Over And Linkage Maps
- When two linked traits crossed, fraction (%) of
recombinants produced varies.
- Genetic loci arranged linearly along chromosome.
- Physical distance between loci dictates frequency of
greater distance greater chance
- Can determine relative positions of multiple genetic loci
and create genetic map. Ex. Location vs. crossing over frequency of Drosophila
