Which scenario breaks the law of segregation?

Some flowering plants appear to have offspring that have traits that are intermediate between those of the parents. Which type of dominance is exhibited by the offspring?

Which blood type could be given as a transfusion for patient with AB blood when the RH factor is unknown?

Mendel’s pea plants had either purple or white flowers. This means that the plants

If Mendel had crossed a true breeding dominant plant with a true breeding recessive plant, in which of the three generations is the recessive trait visible?

two birds are crossed; one that is homozygous for red feathers and one that is homozygous for blue feathers. Purple offspring result due to incomplete dominance. Then, two of the purple offspring are crossed. how many of the offspring will be purple?

In roses, red flowers and long stems are dominant. A rose that is homozygous for both red flowers and long stems is crossed with one that is heterozygous for red flowers and homozygous for short stems. How many offspring will have red, long stems?

Parents with the genotypes AO and AB have a child. What are all the possible blood types of the child?

A plant that has round and yellow seeds (RrYy) is crossed with a plant that has round and yellow seeds (RrYy). What is the ratio of the offspring that will have round and yellow seeds? Key: R = round r = wrinkled Y = yellow y=green
