Chapter 5: Chromosome Mapping in Eukaryotes
Chromosome mapping matching exercise
If two genes on the same chromosome exhibit complete linkage, what is the expected F2 phenotypic ratio from a selfed heterozygote with the genotype a
Each parent produces 2 types of gametes, a
and ab, giving the monohybrid_2 ratio of 3 a
: 1 ab.
Mitotic recombination can occur in
Genes on the same chromosome form a ________ group.
The gametes produced at right result from ________ crossover.
A gene scores 15 second division ascospore segregation and 35 first division segregation in Neurospora. What is the map distance in mu between the gene and the centromere?
d = ((1/2 recombinant asci) / total asci) * 100 =
7.5 / 50
