For simplicity let's consider the influence of 2 genes: A andB, where the dominant allele darkens skin color. Suppose a womanwho is AABb mates with a man who is Aabb.A.

11 Normal No Spac. Styles Paragraph Inheritance APPLICATION Imagine that you are interested in developing a new tomato plant that will inchude the large size and sweetness from one parent and yellow color from another parent. The first parent plant has bland-tasting small yellow tomatoes and the other parent has sweet-tasting large red tomatoes. The chromosomes and alleles of the two plants are shown below. Plant #1: Bland (B), Small (1), Yellow (r) Plant #2: Sweet (b), Large (L), Red (R) R 1 r R Think about what you learned about inheriting traits from the lab to answer these questions. 1. Explain (in sentence form) why it is or is not possible for any of the offspring of these parents to have the sweet gene expressed in its phenotype. To illustrate your explanation, you may use a diagram or use the Punnett squares below to show the genotypes of the possible offspring. Include a percent chance in your answer. 2.

Practice 3, no points. A variety of pea plant known as Blue Pamlico produces a tall plant with blue seeds. A second variety of pea plant called Mulberry Dwarf produces a short plant with white seed. The two varieties are crossed and the seeds are collected. All the seeds are white. When planted, the seeds all produce tall plants. These tall plants are allowed to self-fertilize. For the F2 generation, 94 plants had blue seeds and were tall, 272 plants had white seeds and were tall, 31 plants had blue seeds and were short, and 89 plants had white seeds and were short. a)Which phenotypes are dominant and why? b)What would be the expected distribution of phenotypes in the F2 generation if the alleles of the genes assort independently? c)Perform chi square analysis on the distribution of phenotypes in the F2 generation d) Are these results consistent with the hypothesis of independent assortment? Explain using the results of your chi squared analysis.

Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
