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?

The European land snail, Cepaea nemoralis, exhibits 3 phenotypes in shell color; brown, pink, and yellow. Shell color is controlled by one gene that has only two alleles. Brown (B) is dominant to yellow (b) and pink is the heterozygous condition. In one population of 520 snails, the following color phenotypes were recorded: 236 brown, 231 pink and 53 yellow. What are the actual allelic frequencies?
Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. A population of 30,012 geese includes 9236 dark individuals. Genetic testing reveals that 7636 of the 9236 dark individuals are heterozygous (Dd). According to the Hardy-Weinberg equilibrium, what is the expected number of individuals of genotype Dd? Group of answer choices A.) 14752.40 B.) 13596.09 C.) 8898.56 D.) 3608.26

In fruit flies, the red allele is dominant to the allele for sepia eyes. In a certain population of 1000 fruit flies, 640 flies have red eyes while the remainder have sepia eyes. How many individuals would you expect to be homozygous dominant for red eye color?
A. 0.0025 B. 0.01 C. 0.95 D. 0.99 E. None of the above The common morning glory (Ipomoea purpurea) is highly polymorphic for flower color. Part of this phenotypic variation is due to allelic variation at the P locus. This locus determines whether flowers will be in purple or white color. Further genetic studies showed that the purple color is dominant. Based on a survey, you found that out of a total of 1000 individuals in the population, 922 are purple and 78 are white. Assuming that this population is in Hardy-Weinberg equilibrium, what is the allele frequency for the purple allele? A. 0.078 B. 0.279 C. 0.721 D. 0.922 E. 0.960
Two pea plants are crossed. Both are heterozygous for purple blossom color and both are heterozygous for being tall plants. In pea plants, tall is dominant to short, and purple flowers are dominant to white. Fill out the table below for the probability of each possible phenotype. Report probability as a decimal rounded to four places (e.g. 0.1250, not 1/8 or 12.5%). Phenotype Probability tall purple short purple tall white short white In a population of 150 pea plants, there are 89 tall-purple plants, 25 short-purple plants, 28 tall-white plants, and 8 short-white plants. In order to test if the two traits are experiencing independent assortment researchers would perform a chi squared test. The (null/alternative) hypothesis states that the two genes are independently assorted while the (null/alternative) hypothesis states the two genes are dependent. What is your calculated Chi Squared statistic? When performing a contingency table, do not round your…
