Question 23.
Answer- A. Dominant.
Since both father and mother have a dimple and one if the child id having a dimple as well, it is safe to assume that it is a dominant trait. A dominant trait need only a single copy to be expressed.
Question 24.
Answer- D. DD or Dd
It is a dominant trait single copy of allele D is enough for a person to have a dimple.
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!

1. What does it mean for an allele to be dominant? (i.e. How do you know that Mendel's yellow seeds were considered dominant?) 2. In humans, apparently, the presence of dimples is a dominant characteristic. If the inheritance pattern of dimples is like that of pea color (i.e. two forms, dimples and no-dimples, one dominant and one recessive), described by Mendel, could non-dimpled parents give birth to a dimpled child? If non-dimpled parents do give birth to dimpled children, what...

CONTENT QUESTIONS (answer these for credit) 1. In an experiment to trace the inheritance of two traits in pea plants, a researcher decided to look at height, which is controlled by two alleles. The dominant allele T produces a tall plant while the recessive allele t produces a short plant. Flower color is controlled by one gene with two alleles as well. The dominant allele P produces purple flowers, and the recessive p produces white flowers. If the female parent...

In Mendel's pea plants, the allele for purple flowers (P) is dominant to the allele for white flowers (p). You cross two pea plants that are heterozygous for the flower color trait and obtain 36 peas. When you plant these peas and grow them long enough to see their flowers, you find that 25 of them have purple flowers and 11 of them have white flowers. (a) For this cross, what are the expected values for each phenotype? (1 point)...
