Your biologist friend studies genetics of a new lizard found deep in the rainforest. The allele for a blue skin color, B, is dominant to the allele b which codes for gray-colored skin. He decided to mate a lizard that is heterozygous with a lizard that is gray. What proportion of the offspring will be gray? In your answer: - Show both lizards’ genotypes; - The complete Punnett square;

In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?
In guinea pigs, rough coat is dominant (R) to smooth coat (r), and black coat (B) is dominant to white coat 9. (b). A rough black guinea pig bred with a rough white one produces 29 rough black offspring, 31 rough white offspring, 11 smooth black offspring, and 9 smooth white offspring. Give the genotypes of the parents, the probability for the offspring, and the actual number of each kind of offspring you would expect. Genotype of the rough, black parent?

In rabbits, black hair depends on a dominant allele, B, and brown hair on a recessive allele, b. short hair is due to a dominant allele, S, and long hair to a recessive allele, s. If a true-breeding black short-haired male is mated with a brown long-haired female, describe their offspring. What will be the genotypes of the offspring? If two of these f1 rabbits are mated, what phenotypes would you expect among their offspring? In what proportions?
In Doodlewags (hypothetical creatures), the dominant allele S causes solid coat color; the recessive allele s results in white spots on a colored background. The black coat color allele B is dominant to the brown allele b, but these genes are expressed only in the genotype A-. Individuals that are aa are yellow regardless of B alleles. Six pups are produced in a mating between a solid yellow male and a solid brown female. Their phenotypes are 2 solid black, 1 spotted yellow, 1 spotted black and 2 solid brown. a. What are the genotypes of the male and female parents? Must show work/explain to get full credit. b. What genetic effect is being illustrated in part "a"? Explain in a minimum of 3 sentences.

Hummingbirds have brightly colored feathers on their throats that are used to attract mates. Let's say these feathers come in three different colors red (R), yellow (Y) and grey (g). The red and yellow alleles are codominant when present together, and both red and yellow are dominant when paired with the recessive grey allele. (Hint - this is the same as the ABO blood groups in humans and, is not sex-linked). please show your work. a. A grey female mates with a yellow throated male and she lays 4 eggs. All of the resulting chicks have yellow-colored throats. What is the genotype of the male that fathered the chicks? b. The next year one of the female chicks from the nest above grows up and mates with a male that has both red and yellow feathers. What will be the genotypes and phenotypes of their offspring, and in what proportion? Assume 4 young.
In rabbits grey hair is dominant to white & black eyes are dominant to red. -Cross 2 parents who are both heterozygous for both traits. 1st Question to answer ---- How many of the offspring could have grey hair & black eyes? 2nd Question to answer ---- How many of the offspring could have grey hair & red eyes? 3rd Question to answer ---- How many of the offspring could have white hair & black eyes? 4th Question to answer ---- How many of the offspring could have white hair & red eyes?
In cardinals, a dominant allele R is required for red feathers (r = colorless). In addition, the dominant allele I (of an unlinked gene. is an inhibitor of color (birds with an I allele are colorless; I overrides the effects of R). If a true breeding red cardinal mates with a colorless female (genotype = r/r; I/I): a) What would be the genotype of the F1 progeny? b) What would be the phenotype of the F1 progeny? c) If the F1 progeny are selfed, what is the expected colorless:red ratio among the progeny?
Bronze coloured turkey is controlled by a dominant allele, B. Red coloured turkey is homozygous for a recessive allele bb. Dominant gene N produce normal feather and recessive genotype produce ‘hairy’ feather nn. In a cross between homozygous bronzed coloured turkey with ‘hairy’ feather and homozygous red coloured turkey with normal feather. What are the ratios of F2 progeny with Bbnn genotypes? (I want to check if what i'm doing is correct)
Imagine a cross between a man and a woman having the following genotypes: Genotype of the Husband Genotype of the Wife Aa bb Dd Gg Hh RR Tt X Aa Bb Dd gg Hh Rr Tt Suppose, that the A allele exhibited incomplete dominance over the a allele and the T allele exhibited incomplete dominance over the t allele. In that instance, how many different phenotypes would be possible among the offspring of this same couple?
Scenario A In goats, black fur is dominant to red fur. The gene for this trait can be described as Bb (if you forgot why this is so, go back and reread the background information at the beginning of this exercise). A homozygous black female goat (nanny) is crossed with a heterozygous male (billy). What is the genotype of the billy? What is the phenotype of the billy?
