Answer: D) ALL THE ABOVE
HAVE A BLESSED DAY!!!!! :)
Assuming you mean to type:
"In humans, the allele for dimples (D) is dominant to
the allele for no dimples (d). at another gene locus, the allele for broad
eyebrows (B) is dominant to the allele for broad eyebrows (b)."
Man: Heterozygous for both genes means DdBb
Woman: no dimples, and heterozygous for slender eye-brows
means ddBb
Punnett Square
DB Db
dB db
dB DdBB DdBb ddBB
ddBb
dB DdBB DdBb ddBB ddBb
db DdBb Ddbb
ddBb ddbb
db DdBb Ddbb
ddBb ddbb
Interpretation: anywhere that has a capital letter has the
dominant trait.
Dimples+Broad eyebrows : 6 cases out of 16 (3/8=37.5%)
Dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)
No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
In 1859, Charles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
