Pet rabbits can have a variety of coat colors. Below are the results of a series of crosses performed with black-, blue-, and brown-coated pure lines. Cross Phenotypes of parents F1 phenotypes 1. Black × blue All black 2. Black × brown All black 3. Blue × brown All black If the F1 of cross number 3 is selfed, what is the expected proportion of black kits (baby rabbits) in the offspring? Question 6 options: more than 25%, but less than 50% more than 50%, but less than 75% 25% 75% 50%

The following is known about the inheritance of size and fur color in Holland lop rabbits: Crosses between large individuals only produce large individuals. Crosses between dwarf individuals produce both large and dwarf rabbits in a ratio of 1:2. Such crosses also produce some very small kits (baby rabbits) that generally die within a few days. Crosses between brown rabbits only produce brown kits. Some crosses between black rabbits produce only black kits, whereas others produce both black and brown kits. The size and fur-color phenotypes segregate independently. A large black doe (female rabbit) gives birth to nine black kits―five are large, and four are dwarf. What are the possible phenotypes of the kits' father? Question 6 options: black dwarf or brown large only black dwarf only black dwarf or brown dwarf only black dwarf, brown dwarf, black large, or brown large black dwarf or black large only

In Drosophila melanogaster, the dominant allele Cy results in curly wings. Interestingly, however, temperature also plays a significant role on the wing phenotype.
 Genotype Temperature at which raised Proportion of individual with curly wings Cy+/Cy+(wild type) 17°C 0% Cy+/Cy+(wild type) 26°C 0% Cy/Cy+(mutant) 17°C 15% Cy/Cy+(mutant) 26°C 100% Based on this information we can say that the Question 5 options: expressivity of the Cy allele is temperature-dependent. penetrance of the Cy allele is incomplete. expressivity of the Cy allele is incomplete. penetrance of the Cy allele is temperature-dependent. expressivity and penetrance of the Cy allele are temperature-dependent

In sweet peas, the allele C is needed for color expression (c results in white). The precise color expressed is determined by the alleles R (red) and r (blue). A cross between certain red and blue plants resulted in progeny as follows: 3/8 red, 3/8 blue, 1/4 white. What were the genotypes of the plants crossed? Question 5 options: C/c ; R/r × C/c ; r/r C/c ; R/r × c/c ; R/r C/c ; R/r × C/c ; R/r C/c ; R/r × C/C ; R/R C/c ; r/r × C/C ; R/r

A male mouse of genotype A/a . B/b is testcrossed multiple times. Overall, these testcrosses produce 11 mice of phenotype A B, 81 that are A b, 77 that are a B, and 14 that are a b. Based on these data, the genotypes of the male mouse's parents are most likely: Question 3 options: A/a;B/b and A/a;B/b. Ab/ab and Ab/ab. AB/AB and ab/ab. AB/ab and AB/ab. Ab/Ab and aB/aB.
