Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
In guinea pigs, black hair is dominant over white hair. If a homozygous black guinea pig (father) were crossed with a homozygous white guinea pig (mother), the first generation of offspring would be all black.Match the mother's and father's genotypes and phenotypes to their correct description. 1. mother's phenotype 2. father's phenotype 3. father's genotype 4. mother's genotype a. black b. HH c. white d. hh
In birds, wingspan is determined by two genes, one with complete dominance of one allele over the other, one with additive effects. Birds with genotype aabb has 16 cm long wingspan, whereas those with AABB has 20 cm long wingspan. A cross between AABB and aabb parents produced F1 with 19cm wingspan. Crossing the F1s produced F2 with the following phenotypes (in cm): 20.0 19.6 18.3 20.0 19.1 18.7 18.2 17.3 16.0 19.2 17.8 18.4 19.3 19.5 20.0 19.7 Determine the values of the following: NOTE: write the formula and the final answer Mean of the data Variance of the data Standard deviation According to these data, which wingspans are within one standard deviation of the mean?
Scenario: A plant species has flowers that can be red, pink, or white. Flower color is controlled by one gene with two alleles, A (p) and a (q). Red flowers are produced by AA homozygotes, pink flowers are produced by Aa heterozygotes and white flowers are produced by aa homozygotes. A recent survey of 100 of these plants found the following number of different flower colors: 75 plants with red flowers, 20 pink flowers, 5 white flowers. What are the expected genotype frequencies in this population under Hardy-Weinberg?

A tall pea plant (homozygous dominant) is crossed to a pea plant that is heterozygous for the gene for height. Create a Punnett Square and use it to answer the following questions: What is the genotypic ratio of the offspring? What is the phenotypic ratio of the offspring? Answers are written as genotype; phenotype a) 50% TT : 50% Tt; 100% tall plants b) 1 TT : 2 Tt : 1tt; 75% tall plants : 25% dwarf plants c) 1 TT : 2 Tt : 1tt; 25% tall plants : 50% medium height plants : 25% dwarf plants
In the world of Weeping angels, those with pointy wings are (A_), while those with round wings are (aa). In the efforts to explore this extraordinary species, you wish to determine the genotype of a pointy winged angel. Luckily, you have trapped a round winged angel that you can cross your pointy winged angel with. If the pointy winged angel is homozygous what phenotypic ratio do you expect from their offspring? (Pointy wing: round wing) Group of answer choices a. 1:0 b. 2:1 c. 1:1 d. 3:1
A cross was made between a plant that has blue flowers and purpleseeds and a plant with white flowers and green seeds. The F1 generationwas then allowed to self-fertilize. The following data were obtained:F1 generation: All offspring have blue flowers with purple seeds.F2 generation: 208 blue flowers, purple seeds; 13 blue flowers,green seeds; 19 white flowers, purple seeds; and 60 white flowers,green seeds. Total = 300 offspring.Start with the hypothesis that blue flowers and purple seeds aredominant traits and that the two genes assort independently.Calculate a chi square value. What does this value mean withregard to your hypothesis? If you decide to reject your hypothesis,which aspect of the hypothesis do you think is incorrect (i.e., blueflowers and purple seeds are dominant traits, or the idea that thetwo genes assort independently)?
In humans brown eye color is dominant to blue eye color. Suppose that your mother is homozygous and your father is heterozygous and you have brown eyes. If you have a child with blue eyes, what are the possible genotypes of both of your parents? Group of answer choices Mother bb; Father bb Mother BB; Father BB Mother BB or bb; Father Bb Mother Bb ; Father Bb
