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;

From your research, you discover that in this species of fish, the allele for black color is dominant to orange color. Based on this research, can you determine the genotype of a black fish just by looking at it? Why or why not? Yes, because the recessive allele must have been eliminated by the dominant one. Yes, because the phenotype always expresses all the alleles. No, because you do not know the DNA sequence. No, because it could be either homozygous dominant or heterozygous.
Genetics, Mating took place between males and females of a fruit fly, and individuals appeared With the following proportions and attributes: 25% Female flies with irregular wings and 25% female flies with irregular wings 25% male flies with irregular wings and 25% male flies with irregular wings . . If a symbol for the adjective of regular wings is symbolized by the symbol B and if a symbol for irregular wings with the symbol b, The genotypes of the parents are? 1. bB, Bb 2. bb,Bb 3. XB Y, Xb Xb 4. XbY, XBXb
You are observing a species of mice in which brown fur color is dominant to white fur color. When a brown mouse is crossed with a white mouse, all of their offspring have brown fur. Why did none of the offspring have white fur?
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?
A black guinea pig is mated to a white guinea pig, and they produce 12 black offspring Then, the same white guinea pig is mated to a different black guinea pig, and they produce 7 black and 5 white offspring. What is the best explanation for the difference between these two matings? In your answer, you must include genotypes for the parents and offspring of each cross.
You discover a new allele of a gene important for tail formation in mice. WT mice have long tails, but mice heterozygous for the allele have short tails. When you cross two heterozygous mice together, you obtain a 2:1 ratio of short-tailed mice to long-tailed mice. None of the short-tailed progeny are homozygous. What type of allele results in short tails? A) dominant negative allele B) temperature-sensitive allele C) lethal allele D) partially dominant allele E) incompletely penetrant allele

In cats, white patches are caused by the dominant allele P, while pp individuals are solid-colored. Short hair is caused by a dominant allele S, while ss cats have long hair. A long-haired cat with patches whose mother was solid-colored and short-haired mates with a short-haired, solid-colored cat whose mother was long-haired and solid-colored. What kinds of kittens can arise from this mating, and in what proportions? Show your solution. Explain your answers.
The gene S determines the stripe color of a kind of snake. It has two alleles which are codominant with each other: one allele (S1) causes red stripes, and the other (S2) causes white stripes. What do you predict a heterozygous (S1S2) snake will look like? Select one: a. Assortment of pink, red, and white stripes b. All pink stripes c. No stripes d. Both red and white stripes
The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each.
You know that hamster unicorns (Phodopus monocerus) will be the next big pet craze and are investigating their genetics. In hamster unicorns, fur color is controlled by two loci (B and P). When you cross true-breeding black hamster unicorns with true-breeding pink hamster unicorns, all F1 offspring are black. Hamster unicorns that are B_P_ and B_pp are black, bbpp are pink, and bbP_ are baby blue. What type of epistasis is this? *genetics/bio question*
Suppose you identify a new gene in mice. One of its alleles specifies white fur, another specifies brown. You want to see if these alleles are inherited in a Mendelian pattern, or with incomplete dominance. What crosses would give you the answer?
