Chapter 7 Flashcards
What genes travel together in meiosis?
linked genes
What are groups of linked genes referred to as?
linkage group
What are gametes that only contain the original combinations of alleles in the parents?
nonrecombinant gametes
What is the kids of parents whose gametes match the combination of the parents?
nonrecombinant progeny
What are gametes with new combination of alleles referred to as?
recombinant gametes
What are the children with new combinations of traits as compared to the parents?
recombinant progeny
What is the percentage of recombinant progeny in a cross?
recombination frequency (# of recombinant/total #)
What is the configuration where both wild-type alleles are found on one chromosome?
coupling configuration or cis configuration
What is the configuration where the wild type alleles are on different chromosomes?
repulsion configuration or trans configuration
Chromosome maps calculated by using recombination
genetic maps
Chromosome maps calculated by using physical distanced.
Physical maps
Distance on genetic maps are measured in…
map units (equals 1% difference in recombination rate)
What is another word for map units?
centiMorgans (cM)
What is a test cross between two genes
Two-point testcross
What is a test cross between three genes
three point testcross
