Probability of Inheritance 100%
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? 3:1 1:3 2:2 4:0
3:1
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? 25 percent Tt, 75 percent tt 25 percent tall, 75 percent short 50 percent Tt, 50 percent tt 50 percent tall, 50 percent short
50 percent Tt, 50 percent tt
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? 25 percent 50 percent 75 percent 100 percent
75 percent

TT ´ tt
Which describes the notation Tt for the trait of plant height? homozygous genotype heterozygous genotype homozygous phenotype heterozygous phenotype
heterozygous genotype
Which term describes an organism that has identical alleles for a trait? homozygous heterozygous dominant recessive

Which describes the mating of organisms that have different homozygous alleles for a single trait? monohybrid cross dihybrid cross homozygous cross heterozygous cross
monohybrid cross
Which includes the physical characteristics of an organism? gene allele genotype phenotype
