Recombination Frequencies Can Be Calculated By

question 18

Multiple Choice

Recombination frequencies can be calculated by:

• A) counting the number of recombinant and parental offspring when an individual who is heterozygous for two genes is involved in a testcross.
• B) performing a chi-square test on the F₂ progeny when an individual who is homozygous for two genes is initially crossed to an individual who is homozygous recessive for these two genes.
• C) counting the number of offspring who are expressing the dominant phenotype when a heterozygous individual for two genes is involved in a testcross.
• D) performing a chi-square test of the progeny of a cross between parents who are both heterozygous for the same two genes.
• E) counting the number of offspring that are found in the cross of an individual who is heterozygous for two genes with another parent who is homozygous dominant for one of these genes and homozygous recessive for the other gene.
