1. Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers and the recessive allele (w) codes for short whiskers. a. What is the probability of producing offspring that have short whiskers from a cross of two long-whiskered seals, one that is homozygous dominant and one that is heterozygous? Show your work on the punnett square. % long whiskers % short whiskers b. If one parent seal is a heterozygous long-whisker and the other is short- whiskered, what is the probability that the offspring will have short whiskers? % long whiskers % short whiskers 2. In purple people eaters, one horn (H) is dominant and no horns (h) is recessive. Complete the punnett square to show the cross of two hybrid purple people eaters. Summarize the genotypes and phenotypes of the possible offspring. Possible genotypes of offspring: Possible phenotypes of offspring:

A gardener received a pea plant from her neighbor, and she wants to know its genotype. The neighbor told her it produces round peas, which is a dominant trait (R) to wrinkled peas (r). The gardener performs a test cross and observes that half of the offspring plants produce wrinkled peas. What is the genotype of the plant she received from her neighbor?) homozygous recessive, rr heterozygous, Rr homozygous dominant, RR In pea plants, the allele for round peas (R) is dominant to the allele for wrinkled peas (r). A gardener has a plant he got from his neighbor that produces round peas, but he does not know its genotype. What simple procedure could he do to determine the genotype of his new plant?) Perform a dihybrid cross—if only 1 out of 16 offspring are wrinkled, then the new plant’s genotype is RR. Perform a test cross with a plant that has an Rr genotype—if all of the offspring give round seeds, then the new plant’s genotype is Rr. Perform a test cross…

In this family tree, individuals with the trait are shown in black. Circles represent biological females. Squares represent biological males. Is the trait dominant or recessive? Explain your answer. Is the trait sex-linked? Explain your answer.
In some bizarre-feathered chickens, F is the trait for frizzled feathers while S is the trait for straight feathers. Since both traits are appears to be dominant, what proportion of the offspring would likely show straight feathers? Construct the punnet square and indentify the following: Parents’ genes? Parents’ traits? Genes (genotype)? Feather type? (phenotype)? Genotypic ratio? Phenotypic ratio?
Finish these crosses below:(assume all parents are homozygous for alleles) Cross 1:These are the parents: Sepia Male, Wild Type FemaleWhat are the alleles of the parents? (like Aa and AA / or like XY and XWXW+) Use a Punnett square below to determine the F1 generation phenotypic ratios. What is the phenotypic ratio of the F1? If two F1 individuals mated, what would the F2 phenotypic ratios be?
Finish these crosses below:(assume all parents are homozygous for alleles) Cross 2:These are the parents: Vestigial Wings, Wild Type Body Male; Wild Type Wings and Ebony Body FemaleWhat are the alleles of the parents? (like Aa and AA / or like XY and XWXW+) Use a Punnett square below to determine the F1 generation phenotypic ratios. What is the phenotypic ratio of the F1? If two F1 individuals mated, what would the F2 phenotypic ratios be?
Professor John decided to breed bunnies during stay-at-home because why not. She performed the following cross:Parents:brown fur, gray nose x white fur, gray noseOffspring:3/8 white fur, gray nose1/8 white fur, white nose3/8 brown fur, gray nose 1/8 brown fur, white noseBased on the phenotypes of the offspring, what are the genotypes of the parents? Make sure you define your genotypes (ie B is brown fur, b is white fur)

If two F1 individuals mated, what would the F2 phenotypic ratios be?
Brown fur vs white fur. Say that the alleles for fur color (brown or white) are written using the letter “B” and “b”. The dominant trait is brown, white fur color represents the recessive trait. How would you write out a homozygous dominant individual?

If a homozygous tall pea plant is crossed with a homozygous shortpea plant, what are the possible genotype and phenotype of theoffspring? Legend: T- tall pea plant t- short pea plant Genotypes of the parents: TT x tt Question to answer ff: 1. What is the genotypic ratio? 2. What are the possible phenotypes of the offspring? 3. What is the phenotypic ratio?
Honeybees are unusual in that male bees (drones) have only onecopy of each gene, but female bees have two copies of their genes.This difference arises because drones develop from eggs that havenot been fertilized by sperm cells. In bees, the trait of long wingsis dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyeswas mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and femaleoffspring? What are the phenotypic ratios if we assume an equalnumber of male and female offspring?
