The allele for freckles, F, is dominant among humans. If a woman with freckles (FF) and a man without freckles (ff) have children, what are the possible genotypes of the children?

Ff

Explanation:

F - freckles

f - no freckles

FF x ff

      F       F

f    Ff        Ff

f    Ff       Ff

100% with the dominant allele so 100% chance the children will have freckles

---> the possible genotypes are only Ff

Ff

Explanation:

100% of the children will have freckles and will have the genotype Ff. If you draw out the punnett square, you will see that an F and an f will be in each box. If this is still confusing, I recommend looking up a video of how to use a punnett square, it will make sense. :)

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
