Question

Please help ;-;
In humans, big teeth (B) is dominant to small teeth (t). Freckles (F) are dominant to no freckles (f).
Harry, who is heterozygous for both traits, meets Sally (another heterozygote). Sally has always wanted a child with small teeth and no freckles.
Answer the following questions (and provide all necessary Punnett squares for evidence):

A. What is Harry's genotype?
B. What is Sally's genotype?
C. What is Harry's phenotype?
D. What is Sally's phenotype?
E. Draw a dihybrid Punnett square that predicts Harry and Sally's offspring. Determine the phenotypic ratio of their offspring.
F. Can Sally marry Harry? (In other words, is it possible for them to have the child she desires?)

Answer 1

A. Bb, Ff
B. Bb, Ff
C. Big Teeth, Freckles.
D. Big Teeth, Freckles.
this is just my best guess for the first four answers. itś been years since ive done this so only use these answers if desperate.

Answer 2

Answer:

75

Explanation:

The Punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. The Punnett square below examines the chance of offspring having freckles, which is a dominant trait.

A Punnett square is shown. The columns are labeled Upper F and f. The rows are labeled Upper F and f. Clockwise from upper left the boxes contain: Upper F Upper F, Upper F f, Upper F f, f f.

Based on the Punnett square, what is the probability that the offspring will have freckles?

25 percent

50 percent

75 percent

100 percent
