In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
When you decide to breed your Labrador retriever Molly and sell the puppies, you discover that two of Mollys four siblings have developed a hip disorder that is traceable to the action of a single recessive allele. Molly herself shows no sign of the disorder. If you breed Molly to a male Labrador that does not carry the recessive allele, can you assure a purchaser that the puppies will also be free of the condition? Explain your answer.

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)

You breed two black dogs. It results in 3 offspring, the first which is black, the second which is brown, and the third which is white. Give two genetic explanations as to what could cause their fur color. Make sure each explanation includes two genes and follows along with the provided data. Also, explain the genotype of each color of dog and a ratio of the F2 phenotypes you would expect to see from a dihybrid cross. After you're finished, pick one of the explanations and create a hypothesis for the function of each gene which would explain the molecular basis of the fur color Finally, for each of the two genes, explain how a specific functional difference between the two alleles leads to a difference in their functions
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). 1 What is the genotype of the nanny? Fill input: What is the phenotype of the nanny?
A male dog with the genotype GgBb is crossed with a female dog with the genotype GgBb. Set up a punnet square Note: Gray hair (GG) is dominant over white hair (gg); Black eyes (BB) is dominant over red eyes (bb). (a) How many out of 16 have gray fur and black eyes? (b) How many out of 16 have gray fur and red eyes? (c) How many out of 16 have white fur and black eyes? (d) How many out of 16 have white fur and eyes red? Write the phenotypic ratio.
The gel image below shows 7 alleles, let’s call them 1-7 in order of size, with 1 being the largest and 7 being the smallest. In this sample of 11 individuals, how many times does allele 3 appear? Please type your answer as a number, not a word. ANSWER: In the image below allele 3 appears ? times.
You are conducting an experiment studying sex linked traits. I. The experiment you cross 2 different fruit Flys. The female fruit fly has red eyes and the male fruit fly has white eyes. In the first generation, both male and female Flys both have red eyes. After crossbreeding the offspring, you acquire the data given in the chart for the f2 generation. What would be the expected phenotypic ratio for a male sex linked trait in an f2 generation? Give a chi square analysis to determine if your previous answer is correct.
