Suppose you have two rose plants, both with pink flowers. You cross the two plants and are surprised to find that, while most of the offspring have pink flowers, some have red and some have white.   Explain this result by inventing allele symbols and assigning genotypes to the observed phenotypes.

1. You cross two homozygous parental pea plants. One has purple flowers and is tall, the other has white flowers and is short. All of the F1 plants are purple and short. What are the genotypes of the parents and the F1? If you were to cross the F1 generation, what genotypic and phenotypic ratio would you expect to see in the offspring?

You are studying a population of snapdragon plants on Membata Island. In snapdragons, the dominant allele CR encodes red flowers and the recessive allele CW encodes white flowers. Plants with a heterozygous CRCWgenotype have pink flowers. You have counted 10,000 snapdragon plants on Membata Island. You have recorded that 9025 plants have red flowers, 950 plants have pink flowers, and 25 plants have white flowers. If this population is at a Hardy-Weinberg equilibrium, what are the values of p and...

SHOW YOUR WORK!! In zinnia plants, purple flowers plants X blue flowering plants yield 54 purple and 62 blue offspring. However crossing blue flowering plants X blue flowering plants yield ONLY blue flowering plants. a)What does this tell you about the genotypes of the blue and purple flowered plants? b)Which of the alleles is dominant? Mice can have normal tails or ‘bent’ tails. “Bent” is the dominant x- linked allele (B). The normal allele (b) is recessive. A normal-tailed female...

1. a.) Suppose that you have a batch of red- and white-flowering pea plants. The red-flowering plants are of genotype CC or Cc and the white-flowering pea plants are of genotype cc. All three genotypes CC, Cc, and cc are equally represented in the batch. You pick one plant at random and cross it with a white-flowering pea plant. What is the probability that the offspring will have red flowers? b.) A drug company claims that a new headache drug...

Part A)i n plants, purple flower color is dominant to white flowers color. You crossed a white flowering plant with a purple flowering plant. Out of 236 plants in the offspring, 114 had white flowers and the other 122 had purple flowers. What were the genotypes of the parent plants? A. One plant was heterozygous white and the other heterozygous purple B. Both plants are homozygous C.Both plants are heterozygous D. One plant was homozygous white and the other heterozygous...

(6 pts) In a unique species of bird, feathers may be white, blue, red, or pink. All colors may be true breeding. Color is determined by two unlinked autosomal genes. If true-breeding birds with blue feathers are crossed to true-breeding red-feathered birds, all F1 birds have white feathers. F1 birds were allowed to intercross to generate the F2 generation. Amongst the F2, the following ratio was observed: 9/16 white: 3/16 blue: 3/16 red: 1/16 pink In still another cross, using...

A genetic theory says that a cross between two pink flowering plants will produce red flowering plants a proportion p = 0.25 of the time. To test the theory, 100 crosses are made and 31 of them produce a red flowering plant. At level 10%, we don't have enough statistical evidence to reject the null hypothesis that the cross between two pink flowering plants produce red flowering plants with a proportion of 25%. a. True b. False

Yellow tomatoes are rr. The dominant phenotype for fruit shape is under the control of an allele T, which produces two lobes. Multilobed fruit, the recessive phenotype, have the genotype tt. Two different...

Suppose you have a plant with petals that are normally blue. Suddenly you see some white-petaled plants. Cross 1: You cross the white with the blue and you get all an F1 population that is all blue. In the F2 generation you see a ratio of 101:33 blue to white-petaled plants. Another line of flowers shows pink petals. Cross 2: You cross the pink with the blue and once again the F1 generation shows all plants with blue petals. However,...
