A type of flower called the Rhododendron has a CW allele that leads to red flower color and a Cw allele that leads to white flower color. Rhododendrons with the heterozygous genotype CWCW have flowers with red and white patches. If you crossed two heterozygous Rhododendrons, what flower phenotype ratios would you expect in the offspring? O a) 50% red, 50% white O b) 100% red-and-white patches Oc) 9 red: 3 white: 1 red-and-white patches O d) 25% white, 25% red, 50% red-and-white patches

Suppose a species of tulip has three alleles for the gene that codes for flower color. The CR allele produces red tulips, the CB allele produces blue tulips, and the CW allele produces white tulips. Both CR and CB are dominant over CW, but CR and CB are incompletely dominant with each other, so CRCB heterozygotes have purple flowers. What is the expected phenotypic ratio in the offspring of the following crosses, in the order red : blue : purple : white? Enter your answers as the most simplified ratio (e.g. 1 : 2 : 1 : 1 instead of 2 : 4 : 2 : 2). Enter 0 if none of the offspring from a cross will be a particular color. CRCB × CBCW _____ red : ______blue : ______purple : ______white CRCB × CRCW - _______red : _____blue : _____purple : _____white CRCW × CBCW - _____red : _____blue : _____purple : _____white CRCB × CRCB - red : blue : purple : white
In peas, purple flowers are dominant to white. If a purple-flowered, heterozygous plant were crossed with a white-flowered plant, what is the expected ratio of genotypes and phenotypes among the F1F1offspring? If two of the purple-flowered F1F1 offspring were randomly selected and crossed, what is the expected ratio of genotypes and phenotypes among the F2F2 offspring?
In corn plants, a dominant allele Z inhibits kernel color, while the recessive allele z permits color when homozygous. At a different locus, the dominant allele X causes purple kernel color, while the homozygous recessive genotype causes red kernel color. If corn plants heterozygous for both the Z and X genes are crossed, what are the chances that the offspring will have purple kernels? Enter your answer as a decimal fraction in the box (e.g. 0.25).
To identify the genotype of yellow seeded pea plants as either homozygous dominant (YY) or heterozygous (Yy), you could do a test cross. If 50% of the offspring are yellow-seeded and 50% are green what is the genotype of the parents? A)Yy and YyB)Yy and yyC)YY and YyD)yy and yyE) YY and yy
A pea plant is heterozygous for both pod shape and color. I is the allele for dominant, inflated pod; i is the allele for recessive, constricted pod. G is the allele for dominant, green pod; g is the allele for recessive, yellow color characteristic. Suppose this plant is crossed with a homozygous pea with inflated, green pod, what will be the possible genotype of the offspring? Construct the punnet square, then identify the following: 1. Parents’ genes?2. Parents’ traits?3. Genes (genotype)?4. Shape, color? (phenotype)?5. Genotypic ratio?6. Phenotypic ratio?
If a cross is made between two plants that are heterozygous for two traits (AaBb), then their offspring should follow the 9:3:3:1 ratio. In this case, A is the dominant allele for purple leaves, and B is the dominant allelle for curly roots. If the two parents were crossed to yield 320 progeny, approximately how many plants with purple leaves and curly roots would you expect? Group of answer choices a.180 b.225 c.25 d.50 As part of a lab experiment, you create a two-locus cross between two plants, and you expect to see a 8:4:2:2 ratio of offspring. You determine the phenotype for 160 offspring, and find the proportions 84:38:19:19. If you use a chi-square test to determine whether the offspring do indeed fit this pattern, how many degrees of freedom would the test have? Group of answer choices a.2 b.3 c.83 d.4
In garden peas, the gene for red flowers (R) is dominant over the gene for white flowers (r). If pollen (cells containing sperm nuclei) from the anther (male reproductive organ) of a homozygous red-flowered plant is added to the pistil (female reproductive organ containing the egg) of a white-flowered plant: a. What would be the expected phenotypic and genotypic ratios in the first generation of offspring? b. If two members of the first generation of offspring were crossed, what would be the expected phenotypic and genotypic ratios in the next generation?
Assume that the length of a type of cucumber at maturity is controlled by two genes (A and B), each of which has two alleles. The A and B alleles each add 3 inches of cucumber growth, while the a and b alleles add only 1 inches.

If a heterozygous F1 Tobacco plant was crossed to an albino plant, what is the expected number of green and white plants in the next generation? (show Punnett square) A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring? A man that can roll his tongue is heterozygous for the trait marries a woman that cannot roll her tongue. They have a child. The rolling tongue is dominant to not rolling tongue. What is the man’s genotype for tongue rolling? The women? Show the Punnett square for the child’s genotype Give the probability (percent chance) that the child can or cannot roll their tongue. Oh no! The F1 and F2 generation seed packet labels were mixed around. How would we know which seeds we planted by observing the color of the leaves? (Hint: What are the genotypes of the two generations? What color leaves do they produce in what ratios?)
