Population and Community Dynamics Unit D: Assignment 8A In garden pea plants, the yellow seed colour (Y) is dominant over the green seed colour (y). 3. In a population of 24 pea plants, 15 pea plants are homozygous dominant, 6 are heterozygous dominant, and 3 are recessive. Find the frequency of the following. Show all work and record your response using three significant digits. a. YY genotype: b. Yy genotype: c. yy genotype:

One of the concerns scientists have about genetically selected crops is that some traits for pest resistance may affect the texture of lettuce. What question could be asked to begin this investigation by looking at a measurable dependent variable? * What is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants? O What is the effect of crop selection for pest resistance on the toughness of lettuce leaves? O What is the effect of crop selection for pest resistance on the sale of green salad in grocery stores? What is the effect of crop selection for pest resistance on the texture most preferred for consumption by…

(Practice Hint: Click or tap your finger on the text in the box to make your selection.) A student is researching why domestic cats often have white patches of fur. The student reads the paragraph shown and makes the following conclusion: "Domestic cats with white fur evolved from wildcats through artificial selection." Select the sentence in the paragraph that best supports the student's conclusion. During embryonic development, certain stem cells determine whether a kitten will be born with solid-color fur or with white patches of fur. Wildcats are the genetic ancestors of the domestic cat and have fur color that blends into their environment. Wildcats that eliminated pests and were less afraid of humans were useful for protecting harvested grains. These cats were cared for by humans and were selected to reproduce. O During embryonic development, certain stem cells determine whether a kitten will be born with solid-color fur or with white patches of fur. Wildcats are genetic…
