Which of the following is a "Heterozygous" genotype?

Which of the following is a "Homozygous" gentoype?

In Pea plants, the allele for yellow seeds (Y) is dominant over the allele for green seeds (y).

Take out scrap paper and cross the following parents in a Punnett Square:

Parent 1: Yy

Parent 2: yy

What chance do these parents have of producing a Homozygous recessive offspring (yy)?

According to this Genetic Cross (Punnett Square), the possibility of these parent plants producing a short plant is:

In a certain species of rat, big ears (B) is dominant over small ears (b). If a homozygous big ear rat is crossed with a small ear rat, the genotype of the F₁ generation will most likely be:

*Make a Punnett Square*

In humans, free-ear lobes (F) is dominant over attached ear lobes (f). If two free-ear lobed parents produce an attached ear lobe baby, the genotypes of the parents are most likely:

* Make a Punnett Square for each combo*

In pea plants, yellow seeds are dominant over green seeds. If two plants, both heterozygous for seed color, are crossed, their possible offspring would be expected to have:

*Make a Punnett Square, use any letter you'd like*

When two phenotypes seem to "blend together" we call this type of inheritance:

When two different phenotypes are both "expressed at the same time", we call this type of inheritance:
