Linked genes always exhibita. phenotypes that are similar.b. recombination frequencies of less than 50%.c. homozygosity when involved in a testcross.d. a greater number of recombinant offspring thanparental offspring when involved in a testcross.e. a lack of recombinant offspring when a heterozy-gous parent is testcrossed.b

A testcross includesa. one parent who is homozygous recessive for onegene pair and a second parent who is homozygousrecessive for a second gene pair.b. one parent who is homozygous dominant for one ormore genes and a second parent who is homozygousrecessive for these same genes.c. two parents who are both heterozygous for two ormore genes.d. one parent who shows the dominant phenotypefor one or more genes and a second parent who ishomozygous recessive for these genes.e. one parent who shows the recessive phenotypefor one or more genes and a second parent who ishomozygous dominant for these genes.d6.6. Recombination frequencies can be calculated bya. counting the number of recombinant and parentaloffspring when an individual who is heterozygous fortwo genes is testcrossed.b. performing a chi-square test on the F2 progenywhen an individual who is homozygous for two genesis initially crossed to an individual who is homozy-gous recessive for these two genes.c. counting the number of offspring who are express-ing the dominant phenotype when a heterozygousindividual for two genes is testcrossed.d. performing a chi-square test of the progeny of across between parents who are both heterozygous forthe same two genes.e. counting the number of offspring that are found inthe cross of an individual who is heterozygous fortwo genes with another parent who is homozygousdominant for one of these genes and homozygousrecessive for the other gene.a7.e2 / 25
