- Genetic Problems Read the following genetic problems, and then complete the activities and questions for each problem 1. In the pea plant, the green pod color allele is dominant to the yellow pod color allele. o Set-up a monohybrid cross between a pea plant that is heterozygous and a true-breeding yellow pod pea plant. o What percentage of the offspring produced from this cross would you expect to have yellow pods? 2. Within a mouse population, the black fur allele (B) is dominant to the white fur allele (b) and the short whisker allele (S) is dominant to the ngs long-whisker allele (s). o A heterozygous black-furred short-whiskered mouse is crossed with a homozygous white-furred long-whiskered mouse. o What percentage of the offspring will be black-furred with long whiskers? 3.

Draw if needed I need to visual to understandarrow_forwardA 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?arrow_forward
- Problem) A university student is studying the inheritance of 2 genes of pea plants. Color of plant: Blue is dominant (B), and yellow is recessive (b) Spikes or no spikes: Having spikes is dominant (G), and having no spikes is recessive (g). Which of the following findings would indicate to the student that these two traits are located close together on the same chromosome? a) The traits show independent assortment b) All gametes of a double heterozygous individual (BbGg) are either BG or bg c) A double heterozygous individual has four types of gametes in approximately equal proportions: BG, Bg, bG, and bg d) Student finds that there is frequent crossing over between the 2lociarrow_forwardThank you.arrow_forwardZOOM 4) Color-blindness is caused by an X-linked recessive allele. A color-blind woman marries a man with normal color vision. What would be their children's phenotypes (in percent)? What percent of their offspring will be females with normal color vision, but who are carriers for the condition?arrow_forward
