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

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*
Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele have sharp spines, whereas homozygous recessive cactuses have dull spines. At the same time, a second gene, N, determines whether or not cactuses have long or short spines. Homozygous recessive cactuses have short spines. A cross between a homozygous sharp-long cactus and a dull short-spined cactus would produce what percentage of sharp-long cacti?

Suppose a mutant fruit fly with blue eyes was recently discovered. It is later determined that the blue eye trait is recessive to the wild-type red eye trait. What is the most common way to represent the mutant and wild-type alleles?. Choices are Mutant: Bl, bl Wild-type: Bl+ , re, bl+, or wt
In a mammal, there are two; unlinked genes that determine tail length and curliness. The dominant L gene encodes long tails and the recessive l, short tails. For animals that have long tails, the C gene determines curliness, with the dominant C allele giving curly tails, while the c allele results in straight tails. Short tails are too short to curl. In a cross LlCc x LlCc, (Long, Curly tails) the tails of the progeny will appear in what phenotypic ratio? A. 9 Long & Curly: 3: Short & Straight 4 Long & Straight B. 9 Long & Curly: 3 Long & Straight: 3 Short & Straight: 1 Short & Curly C. 9 Long & Curly: 3 Long & Straight: 4 Short & Straight D. 9 Long & Curly: 6 Long & Straight: 1 Short & Curly

In pea plants, the allele for round seeds (R) is dominant and the allele for wrinkled seeds (r) is recessive. Under what conditions would we observe wrinkled seeds in a pea plant?A. When the plant has a genotype RRB. When the plant inherits a dominant allele from both parentsC. When the plant inherits a recessive allele from both parentsD. When a plant has a heterozygous allelic pair of the gene for seed shape
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?

We are making a hypothetical dog breed: Worgi (wolf, corgi mix). Assume ear length and tail shape in Worgis are each controlled by a single gene and long ears and a curly tail are dominant phenotypes. Alleles and phenotypes for your drawings: L-long ears, l-short ears, C-curly tail and c-straight tail A. Predict the gametes that a Worgi with long ears and a curly tail will produce if ear length and tail shape are linked traits. B. Predict the gametes that a Worgi with long ears and a curly tail will produce if ear length and tail shape are unlinked traits. C. Draw a homologous pair separating during anaphase I. Label the ear length and tail shape gene. Explain why the gametes from part A and B are similar and/or diffferent.

How do you know? 6. a) b) (4 --1 per individual ) Label everyone's genotype. In some cases you may have to say there is an X probability of, for example, BB and a Y probability of Bb. Hint: these probabilities might not be in halves or fourths. c) baby? No qualifiers!
