Two rabbits, one with a brown coat (cc) and the other with a white coat (cc), are crossed. what are the likely results of this cross? . a) all of the offspring will have white coats, and none will have brown coats.. b) one-half of the offspring will have brown coats, and one-half will have white coats.. c) all of the offspring will have brown coats, and none will have white coats.. @petiteme

B

Explanation:

We can see that the allele coding for the brown coat is heterozygous (Cc) and that of the white coat is homozygous (cc). Since, in the heterozygous state, the brown coat was phenotypically expressed, it means that the allele coding for the brown coat (C) is dominant over the white (c).

To the cross, we have:

Cc × cc

The offsprings will be Cc, Cc, cc and cc

We have two heterozygous dominant and two homozygous recessive offsprings

The 2 heterozygous offsprings will phenotypically have a brown coat because it is the dominant allele while the other 2 homozygous offsprings will have a phenotypically white coat.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
