Please answer both pages

On a separate piece of paper, answer the Genetics Problems allele (a) that is recessive to the ailele for nomal metabolism o following questions. Be sure to SHOW ALL WORK c. If Sally of Sally, her mother, hor father, and her brother humans, the allele for six If both that their frst child will have alkaptonuria? ngers, what is the probabity that their first child wil be 'normar (have five percentage of their children should to the allele for five six fingers and the mother has Sive fingers, what black color color (b). The trotting gait (T) dominates the pacing gate (), A cross is made pacing gait and a horse homozygous for both chestnut color and the trotting gait. b. If two About 70% of Americans perceive a bitter taste from the chemical results from a dominant allele (T) Albinism is also a single locus (inf pigment is dominant (A) and the allele for lack of pigment is recessive (a). A normally pigmented woman who cannot taste Prc has a father who is an albino taster. She maries a homozygous, normally pigmented man who is a taster but 4. ratio of their offspring? (PTC). The ability to taste this alleles () and not being able to taste PTC is the result of having two one gene) trait with patients displaying a lack of pigment. The allele for normal mother that does not taste PTC. a. What are the b. What percentage of the children will be albinos? What percentage of the children will be non-tasters of PTC? a male with type O mates with a female who has type A blood. The female's mother had type A blood and her father c. had type B. What is the probabiliy that their first child will ave type A blood?What is the probability that their third child will have type O blood? 5. Assume color. If an oval white radish is crossed with a round red radish that is heterozygous for color, what percent of their offspring should be round and white? 6. In the radish plant, the long and round traits are incompletely dominant and result in an oval shape. Red color dominates white for these two ch both) is crossed with a plant containing sweet fruit that is heterozygous for the (S) gene. 7. In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yelow spots(S) are dominant over no spots (s). The genes assort model, the a. What phenotypic ratio would you expect from this cross? b. If you produced 500 plants from these parents, how many of the 500 would you expect to be sweet and yellow? 8. Two parents have the following genotypes: BbHhff and Bbhhf. What is the probabity that the olowing parents will produce o a child with a bbHhFIgenotype?
