swat32

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%)

What best describes the difference between paracentric and pericentric inversion?
topjm [15]

Answer:

The answer is B.

Explanation:

Paracentric and Pericentric Inversions both are terms used to describe the action of inversing a part of the chromosome. But the main difference between the paracentric and pericentric inversions is that pericentric inversion, unlike the paracentric inversion, does include the centromere in the inversion process. So the answer is B, which is zero for paracentric inversion.

I hope this answer helps.
