Chapter 5 Flashcards
(5 cards)
1
Q
linkage
A
the proximity of two or more markers on a chromosome; the closer together the markers are, the lower the probability that they will separate by recombination. Genes are linked when the frequency of parental-type progeny exceeds that of recombinant progeny.
2
Q
locus
A
a designated location on a chromosome
3
Q
chiasma
A
observable regions in which nonsister chromatids of homologous chromosomes cross over
4
Q
recombination
A
the process by which offspring derive a combination of alleles different from that of either parent; the generation of new allelic combinations.
5
Q
tetratype
A
a fungal tetrad carrying four kinds of haploid cells; two different parental class spores and two different recombinants.
