Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for the trait. If the stem characteristics are determined by a single gene, what is the expected percent chance of having hairy stems if crossing two tomato plants that are heterozygous for hairy stems?

The dominant trait for height in pea plants is for the plant to be tall, and the dominant shape for the peas is round instead of wrinkled. Select all the options below that would indicate offspring that is short and round.

In Mendel’s pea plants, plant height is controlled by a single gene in which the tall allele is dominant to the short allele. Complete parental genotypes that would produce 75% tall pea plants and 25% short pea plants? For example: tt x tt would produce 100% short pea plants
