1. A pure line Brown coat goat is crossed with pure line White coat goat. Consider the Brown coat is dominant over white coat. a. What is the result (F1) of this cross? b. What is the result when 2 F1 hybrid from (a) is crossed? Give the phenotype, genotype and their ratio. Make sure the phenotype and genotype were aligned with its ratio.

6. The following F2 phenotypic data was obtained from a testcross using an F1 offspring. Assume red and tall are dominant wildtype phenotypes, and white and short are mutant phenotypes. Red, short 578 Red, tall 54 White, tall 603 White, short 48 What is the genotype of the F1 offspring used in the cross?   Question 6 options:   WS/ws   Ws/wS   WwSs   It is not possible to determine from the data set

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.

1. Use the following information to answer the question: Parental cross is RrYy x RrYy                                                                                                       Seed Shapes are R-round, r-wrinkled                                                                                                       Seed colors are Y-yellow, y-green   Based on the information given, what is the phenotype ratio of the offspring of this cross? 2. A pea plant heterozygous for height and seed color (TtYy) is crossed with a pea plant heterozygous for height but homozygous recessive for seed color (Ttyy). If 80 offspring are produced, how many are expected to be tall and have yellow seeds?  3. What is the chromosome theory of inheritance? How does this theory explain Mendel's results? 4. A cross between two organisms heterozygous for two different genes (AaBb) results in a 9:3:3:1 phenotype ratio among the offspring. Is the offspring's genotype ratio the same? Explain your answer.…

3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born. Homozygous t/t is normal, with normal tail. A cross between two short-tailed mice produces a litter of 5 pups. a). What are the genotype(s) of the two short-tailed mice used in the cross? b). What are the possible genotypes and phenotypes of the 5 pups? What are their perspective ratio?

A. 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 F, generation are all gray. In the F, generhtion there are three gray to one black (3/4 gray : 1/4 black). 1. Diagram the F, cross, using G = gray, g = black.

2. Complete the following cross: a. In pea plants, the dominant allele T gives a tall phenotype while the recessive allele t has a dwarf phenotype. Draw the Punnett square by clicking on and placing the correct capital or lowercase letter combination in the boxes. In this example, eggs and sperm can be placed on either top or side Tt x Tt What is the genotype ratio? What is the phenotype ratio?

1. In guinea pig, fur color is determined by one gene, and fur length by another independently segregating gene. The black fur allele (B) is dominant to brown fur allele (b) and the short allele (S) is dominant to long fur allele (s). From progeny listed in the following table, provide the probable genotype for the parents of each cross. Phenotype of Progeny Black short black long brown short Parents Black short X Black short Black short X Brown long Black long X Black long 90 17 0 32 16 35 29 14 0 brown long 8 15 2. A mouse with the genotype BbccEeFf is mated with another mouse with BBCCEEFF genotype. What is the probability of obtaining the following genotype in the progeny? a. BBCcEeFF b. BbccEEFf C. BbccEeFF 12 3. Determine the type of gametes that are formed from the following individuals with the given genotype? A. AaBbCc B. AABBCc C. AABbCe

4) The round pea seed allele (R) is dominant, while the wrinkled pea seed allele (r) isrecessive. A heterozygous round-seeded pea plant is crossed with a wrinkle-seeded peaplant. Use a Punnett Square to solve the following: a. Determine the predicted genotype ratio of the offspring. b. Determine the predicted phenotype ratio of the offspring. c. If this cross produced 50 plants, how many plants would you predict would bewrinkle-seeded pea plants?  please if punnet square needed write down the P G and F1 also thanks

1,Show the cross between two people with Type AB blood. What is the genotypic and phenotypic outcome of such a cross?   2. Incomplete dominance = If a Red (RR) and White flower (rr) were crossbred, resulting in 100% Rr, what phenotype(s) would been seen according to the rules of IN-complete dominance?   3. Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.”   Mother’s genotype: _______ Father’s genotype: _______ Baby’s genotype: ______ or _______ Was the baby switched? ____________________________________________________
