Week 9: Probability of Inheritance Answers

What is one of the reasons why Gregor Mendel chose to study pea plants?

Why did Gregor Mendel choose to use purebred plants in his experiments?

Purple flowers are dominant over white flowers. A heterozygous purple flower is crossed with another heterozygous purple flower. What will the ratio of purple to white be?

The offspring of a particular cross are 100 percent heterozygous for the trait of plant height. What were the most likely genotypes of the parents?

Which describes the mating of organisms that have different homozygous alleles for a single trait?

Which term describes an organism that has identical alleles for a trait?

There are two different alleles for flower color, P and p. The image shows a white sweet pea with a genotypeo of pp.What can you surmise from the labeled image?

A dihybrid cross is created from plants that are heterozygous for both round seeds and yellow seed color. What is the ratio of offspring that have round seeds and yellow seed color?

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. In this cross, tallness (H) is dominant to shortness (h).Based on the Punnett square, what is the phenotype of the offspring?

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.Based on the Punnett square, what is the probability that the offspring will have freckles?
