Probability of Inheritance Answers

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?

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?

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

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?

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?

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

There are two different alleles for flower color, P and p. The image shows a purple sweet pea that is labeled with its two alleles for petal color.Which is the genotype of the sweet pea?

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?

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?
