The remaining questions go together. You are given a pea that produces round, yellow seeds (both dominant traits), but its genotype is unknown. You conduct a testcross to determine the genotype at both loci, and find that the offspring have the following ratios of phenotypes: ¼ round, yellow, 4 round, green, ¼ wrinkled, yellow, ¼ wrinkled, green What is the genotype of the individual of known genotype in the testcross? rryy RRYY RrYy O rrYy OR_Y_ O Rryy

. A snapdragon plant that bred true for white petals wascrossed with a plant that bred true for purple petals, andall the F1 had white petals. The F1 was selfed. Among theF2, three phenotypes were observed in the followingnumbers:white 240solid purple 61spotted purple 19Total 320a. Propose an explanation for these results, showinggenotypes of all generations (make up and explain yoursymbols).b. A white F2 plant was crossed with a solid purple F2plant, and the progeny werewhite 50%solid purple 25%spotted purple 25%What were the genotypes of the F2 plants crossed?

A heterozygous tall yellow plant is crossed with a homozygous short green. What will be the genotypes 3. and phenotypes, and probabilities of the first generation? Genotype of the heterozygous tall, yellow plant Genotype of the homozygous short, green plant Genotypes Phenotypes Right handedness (R) is dominant over left (r) Browyn eves (B) are dominant over blue (b). A man who is blue eyed and right handed, whose father was left handed, married a left handed woman with brown eyes, whose mother was blue eyed. What are the possible phenotypes and genotypes of the offspring and the probability for each? 4. Genotype of the man Genotype of the woman Genotypes Phenotypes What is the probability of getting right handed offspring? What is the probability of getting blue eyed offspring? What is the probability of getting offspring heterozygous for both traits? What is the probability of getting offspring that are homozygous dominant?
