The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ
uals with two A2 alleles (A2A2) are white, and individuals with one of each allele (A1A2) are mottled. In a cross between two black flowers, what is the probability of getting a mottled offspring? (2
We know that an individual with two A1 alleles (A1A1) are black, so if two black flowers are crossed that means two flowers with A1 (black)alleles, as these flowers do not have any A2 allele to give a mottled flower, the only type of flower that will come out from this cross is a black one.
solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume. change of state: When matter is converted from one of the three states (example: solid, liquid, or gas) to another state.
