Probability of Inheritance Answers

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?

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?

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

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?

Which describes the notation Tt for the trait of plant height?

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?

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?

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?

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?

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

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?

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

Which includes the physical characteristics of an organism?
