Probability of Inheritance Answers

A plant can produce either purple flowers or white flowers. The purple flower color is dominant over the white flower color. What is the ratio of the offspring with purple flowers to the total number of offspring if two plants that are heterozygous for purple flowers are crossed?

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?

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

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

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

Gregor Mendel crossed homozygous tall plants (TT) with homozygous short plants (tt). All the resulting offspring were tall. From these results, what conclusion did Mendel draw?

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

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?

In pea plants, tallness (T) is dominant to shortness (t). What are the predicted percentages of the genotypes of the offspring if a homozygous short plant is crossed with a heterozygous tall plant?

Which includes the physical characteristics of an organism?

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?

Mendel crossed two plants that were heterozygous for the trait of flower color. Which genotypes could he have used to represent the cross?

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?

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?
