11. In his original work on the genetics of garden peas, Mendel found that yellow seed color (YY, Yy) is dominant over green seeds (yy) and that round seed shape (RR, Rr) is domínant over shrunken seeds (rr). Mendel crossed pure-breeding (homozygous) yellow, round-seeded plants with green, shrunken-seeded plants. a. What will be the genotype and phenotype of the F, produced from such a cross? genotype. phenotype. b. If the F, plants are crossed, what will be the expected phenotypic ratio of the F2 generation?

5. A husband and wife have typical vision, although both of their fathers are red-green colorblind (an X-linked recessive trait). From this information, determine the appropriate symbols for the wild-type and color-blind alleles and write the genotypes of the husband and wife. a. b. What is the probability that the couple will have a son with typical vision? C. What is the probability that the couple will have a daughter with typical vision? d. What is the probability that the couple will have a son with colorblindness? e. What is the probabilityt the the couple will have a daughter with colorblindness?

In a cross between a black and a white guinea pig, all members of the F₁ generation are black. The F2 generation is made up of approximately 3/4 black and 1/4 white guinea pigs. Let's call the gene associated with guinea pig color (A). What are the parent genotypes? A. (AA) and (AA) B. (AA) and (aa) C. (Aa) and (aa) D. (Aa) and (Aa) E. There is more than one correct answer What are the F1 genotypes? A. All (AA) B. All (Aa) C. ½ (Aa) and ½ (aa) D. 14 (AA), 1 (Aa), ¼ (aa) E. 1 (AA) and ½ (Aa)

5. The pedigree below traces the inheritance of Albinism, a genetic disorder. Affected individuals, indicated here by the coloured circles and squares, are unable to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair colour. Does Albinism appear to be caused by a dominant allele or by a recessive allele? Fill in the genotypes of the individuals whose genotypes can be deduced. What genotypes are possible for each of the other individuals? Explain! Naruto Hinata Reiner Asta Hange Mikasa Eren Historia Luffy Nezuko Zenitsu Tanjiro Son Goku

Mendel crossed Parental true-breeding (homozygous) Purple flowered peas with true-breeding (homozygous) White flowered peas, and all the F1 offspring were Purple flowered. What was the phenotype and genotype of the F1 hybrids? 3/4 purple, PP: 1/4white pp .1/2purple. PP 1/2 whitce pp purple. PA purple Pp 近

8. In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). Similarly, the allele for straight hair (H) is dominant over the allele for having rough hair (h). Pure breeding rough haired guinea pigs with black fur were crossed with pure breeding straight haired guinea pigs with white fur. a. State the genotype and the phenotype of the F1 individuals produced as a result of this cross.b. Two F1 offspring were mated together. Calculate the expected ratio of phenotypes in the F2 generation.c. Show the completed Punnett square below.

II. Solve the following problems. 1. Mendel crossed a plant that was heterozygous for height and heterozygous for pea shape with a plant that was homozygous dominant for height and heterozygous for shape. What are the possible genotypes and phenotypes of the offspring? Dominant for height= T (tall) Recessive for height =t (short) Dominant for pea shape = R (round) pea %3D Recessive for pea shape =r(wrinkled) P1: Genotypes: Phenotypes: Genotypic Ratio: Phenotypic Ratio
