Linkage and Recombination II Flashcards
0
Q
Distances on genetic maps are measured in:
A
map units (m.u.) or centimorgans
1
Q
How are genetic maps calculated?
A
By using recombination frequencies
2
Q
How are physical maps calculated?
A
By calculating physical distances along the chromosome, using numbers of base pairs
3
Q
What are types of crossovers?
A
Two types of single crossovers
Double crossover
4
Q
In all types of crossovers, there will always be what?
A
Two recombinant chromosomes and two non recombinant chromosomes
5
Q
In the recombinant chromosomes resulting from the double crossover, the alleles are:
A
The outer two alleles are the same as the nonrecombinants
but the middle allele is different
