Normal Spac. Styles agraph Inheritance APPLICATION Imagine that you are interested in developing a new tomato plant that will include 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) 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. Explain whether or not it is possible to create a tomato plant with sweet, large, yellow tomatoes from a cross of Plant #1 and Plant #2. 3. After years of disappointment, you find one plant out of thousands in your greenhouse that is producing large yellow tomatoes! How might this have happened?

Aav AaBbCc Normal No Spacing Heading 1 Paragraph Styles In man, two abnormal conditions, cataracts (C) in the eyes and excessive fragility (F) in the bones, seem to depend on separate dominant genes located on different chromosomes.

Her father had normal bones. 11. What is the genotype of the man with cataracts and nomal bones? What is the genotype of the woman with normal vision and fragile bones?

. An allotetraploid species has a genome composed oftwo ancestral genomes, A and B, each of which havea basic chromosome number (x) of seven. In thisspecies, the two copies of each chromosome of eachancestral genome pair only with each other duringmeiosis. Resistance to a pathogen that attacks the foliage of the plant is controlled by a dominant allele atthe F locus. The recessive alleles Faand Fbconfersensitivity to the pathogen, but the dominant resistancealleles present in the two genomes have slightly different effects. Plants with at least one FAallele areresistant to races 1 and 2 of the pathogen regardlessof the genotype in the B genome, and plants with atleast one FBallele are resistant to races 1 and 3 of thepathogen regardless of the genotype in the A genome.What proportion of the self-progeny of an FA Fa FB Fbplant will be resistant to all three races of the pathogen?

The production of pigment in the outer layer of seedsof corn requires each of the three independently assorting genes A, C, and R to be represented by at leastone dominant allele, as specified in Problem 64.
