What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
In dogs, dark coat color is dominant over albino, andshort hair is dominant over long hair. Assume that theseeffects are caused by two independently assorting genes.Seven crosses were done as shown below, in which D andA stand for the dark and albino phenotypes, respectively,and S and L stand for the short-hair and long-hairphenotypes.Number of progenyParental phenotypes D, S D, L A, S A, La.

We have dealt mainly with only two genes, but the sameprinciples hold for more than two genes. Consider thefollowing cross:A/a ; B/b ; C/c ; D/d ; E/e × a/a ; B/b ; c/c ; D/d ; e/ea. What proportion of progeny will phenotypicallyresemble (1) the first parent, (2) the second parent,(3) either parent, and (4) neither parent?b. What proportion of progeny will be genotypically thesame as (1) the first parent, (2) the second parent,(3) either parent, and (4) neither parent?Assume independent assortment.
You carry out a trihybrid cross (a cross in which the parental plants differ for three characters) between a tall pea plant with round, yellow seeds (TT RR YY) and a short pea plant with wrinkled, green seeds (tt rr yy). The parental plants are homozygous for all of the three characters. They are crossed to produce the F1 generation. Tall, round, and yellow are the dominant traits for each character. What will be the phenotypes of the F1 generation?
In the cross TtPpAa x ttPpaa, what fraction of offspring are predicted to be homozygous recessive for at least two of the three traits?
Three recessive traits in garden pea plants are as follows: yellowpods are recessive to green pods, bluish green seedlings are recessiveto green seedlings, creeper (a plant that cannot stand up) isrecessive to normal. A true-breeding normal plant with green podsand green seedlings was crossed to a creeper with yellow pods andbluish green seedlings. The F1 plants were then crossed to creeperswith yellow pods and bluish green seedlings. The following resultswere obtained: 2059 green pods, green seedlings, normal151 green pods, green seedlings, creeper281 green pods, bluish green seedlings, normal15 green pods, bluish green seedlings, creeper2041 yellow pods, bluish green seedlings, creeper157 yellow pods, bluish green seedlings, normal282 yellow pods, green seedlings, creeper11 yellow pods, green seedlings, normal Construct a genetic map that indicates the map distances betweenthese three genes?
