9. Make a pedigree for each of the following situations. For each individual, write the individual's genotype (when possible) next to the individual's symbol (e.g. O xty, I Gg): a. Two parents do not have cystic fibrosis and they have a daughter with cystic fibrosis and a son who does not have cystic fibrosis. The daughter grows up and she mates with a male who does not have cystic fibrosis. Their only child is a boy and he has cystic fibrosis. b. A man with hemophilia mates with a female without hemophilia. They have one son and one daughter. The daughter has hemophilia and the son does not have hemophilia. The son grows up, and he marries and mates with a female. Their only child is a boy, and he has hemophilia.

Provide a Punnett square demonstrating this dihybrid cross.What are the ratios for each genotype in the resulting offspring? What are the ratios for each phenotype? Your answer should clearly indicate the genotype and phenotype each portion of the ratio is referring to
type P = n! (p)* (q)"* х! (n - х)! Practice Problem: You cross a true-breeding pea plant with red flowers to a true-breeding pea plant with white flowers. All of your offspring have red flowers. Which gene is dominant? Why? What is the genotype of your offspring? You then cross the offspring to each other. What ratio do you expect? Why? You count 1000 plants and look at their flowers. Your results are as follows: 740 red 260 white Does this follow a simple Mendelian inheritance pattern? Why or why not? DADT 2 MEA SUDI ND D LUT IONS

Create a dihybrid cross and determine the expected phenotypic percentages of the offspring of two corn plants both of which are heterozygous for colour and texture (RrTt X RrTt). Don't forget to include clear let statements, and follow the all six steps taught on solving genetics problems. insig moni nellog: bna. zoom
For all of the testcross problems, indicate parental phenotypes, genotypes and gametes; indicate genotypes and phenotypes off offspring. Show your work on a separate sheet(s) of paper! I. Complete Dominance House mice have two coat colors; gray (agouti, or wild type) and black. When true-breeding gray mice are crossed with true-breeding black mice, the F1 generation are all gray. In the F2 generation there are three gray to one black (3/4 gray : 1/4 black). Diagram the F1 cross, using G = gray, g = black. What genotypic and phenotypic ratios would you expect if you crossed a pure breeding gray mouse with a heterozygous mouse? Two gray mice with unknown ancestry are crossed. Can you determine from the phenotypes of their offspring if the parents are homozygous or heterozygous? Explain how.
Purple flowers are dominant to white flowers. Identify the phenotypefor the following genotype Ff, FF, ff and determine if the genotype is heterozygous or homozygous. * For each row, you should select two columns. Purple flowers White flowers Heterozygous Homozygous Ff FF ff Brown eyes are dominant to blue eyes. Identify the phenotype for the following genotype BB, Bb, bb and determine if the genotype is heterozygous or homozygous. * 口ロ口
S (smooth) is dominant to s (hairy) L (long pod) is dominant to I (short pod) (Ll is medium length) 7. Given this cross: Yy RR Bb SS LI (male) cross with yy RR Bb Ss Ll (female) a. How many different gametes can be formed by the female plant? b. How many different genotypes are possible in the F1 offspring? c. How many different phenotypes are possible in the F1 offspring? d. What percent of the F1 individuals will be: i. green, bitter, and smooth. ii. hairy, medium, and sweet iii. round, bitter, and long. 8. Two babies in a maternity ward have lost their identity bands, and there is some confusion about their footprint records. Baby #1 is type A blood; #2 is type B blood. If you are one of the mothers and your blood type is 0, which one of the following statements applies. Explain your answer. Neither baby could be yours. The type A baby is yours. The type B baby is yours. Either baby could be yours. 9. In cocker spaniels, the following genotypes and phenotypes are found: AABB =…
What phenotypes in what ratio would be expected in the F2 generation of the cross with the following information: The genotype of homozygous black, long haired rabbit is BBhh The genotype of homozygous brown, short haired rabbit is bbHH The gamete of homozygous black, long haired rabbit is Bh The gamete of homozygous brown, short haired rabbit is bH F1 progeny is BbHh (heterozygous black, short haired rabbit)
In onions, male sterility is due to the interaction of a chromosomal allele pair hh and "sterile" (S) cytoplasm. All other combinations (i.e. HH/Hh and "sterile" cytoplasm, HH/Hh or hh "fertile" (F) cytoplasm) result in male-fertile plants. The male-sterile trait is incorporated into inbred lines to produce hybrid F, seed on a commercial scale. b) Briefly outline the method of producing hybrid seed (heterozygote) for the commercial crop.
