Probability of Inheritance Answers
Which includes the physical characteristics of an organism?
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 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?
Mendel crossed two plants that were heterozygous for the trait of flower color. Which genotypes could he have used to represent the cross?
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?
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 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?
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?
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?
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?
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?
