Answer:

25% Homozygous Rose Comb, 25% Homozygous Single Comb and 50% Heterozygous Rose Comb.

Explanation:

For a homozygous rose combed rooster (RR) and a homozygous single combed hen (rr), their first offspring F1 will be 100% heterozygous rose combed which has the genotype of Rr.

If the F1 generation are allowed to mate only among themselves, the second generation offspring, F2, will have 3 different genotypes which are homozygous rose comb (RR), homozygous single comb (rr) and heterozygous rose comb (Rr).

I hope this answer helps.

A recent law school graduate was offered a job as an aide by a state legislator. The legislator told the graduate that before sh
IRINA_888 [86]

Answer:B Yes, as to the promise to respect the flag.

Explanation:The graduate is correct in terms of the promise to respect the flag , this part is unconstitutional so no one is forced to swear by it. However the she is wrong in the other two promises because those two are constitutional, The supreme Court does require that government employees uphold an oath to oppose any violent action that is meant to overthrow the government and they are required to uphold the state and Federal Constitution. This them makes the option A and C incorrect because in this regard the graduate isn't correct. Government can't however force an individual to show respect to the flag because someone may refuse to do due to their religious beliefs and as we know everyone has the right to freely pursue their religion of choice. Hence B is correct and D is incorrect.
