Purple flowers are dominant to white flowers. Using the allele "p", write the genotype for a white flower.
If P = purple flowers and p = white flowers, then white flowers has a genotype of pp.

A long tailed dog (L) and a short tailed (S) dog mate to produce all medium length tailed puppies. What is the genotype of the medium length tailed puppy?
LS or SL

Unattached earlobes (U) are dominant to attached earlobes and tongue rolling (T) is dominant to not being able to roll tongue. The wife is homozygous dominant for unattached earlobes and heterozygous for tongue rollling. The husband has attached earlobes and is homozygous dominant for tongue rolling. Write the parents genotypes?
If U = unattached earlobes and u = attached, and T = tongue rolling and t = no tongue rolling then the wife is UUTt and the husband is uuTT.

Tall stems are dominant to short stems. The offspring are all short stemmed. Using the allele "t", what are the genotypes of the parents? You can set the timer to 2 minutes!
If T = tall stem and t = short stem, then both parents are tt.

Tall stems are dominant to short stems. Using the allele "t", write the possible genotypes to represent tall stems
If you are using T for tall - TT or Tt

Tall stems (T) are dominant to short stems and round seeds (R) are dominant to wrinkled seeds. One parent is heterozygous for tall stems and has wrinkled seeds. What are the 4 gamete combinations for this parent
The parent's genotype is Ttrr. Use foil or a small punnett square to get the four gamete combinations which are: Tr, Tr, tr, and tr.

Long hair is dominant to short hair in cats. Two cats mate and ALWAYS produce long haired kittens. One parent has short hair. Using the allele "h", what is the genotype of the other parent? You can set the timer to 2 minutes!
H = long hair and h = short hair. If one parent has short hair (hh), then the other parent must be HH to always have kids that have long hair.
