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.

What is the role of society in conflict management​
VMariaS [17]

Explanation:

The form ethnic conflict takes, be it, religious, linguistic, racial, tribal does not seem to alter its intensity, longevity, passion and relative intractability, their emphasis on the ascriptive and cultural core of the conflict, imagined or real, and they distinguish it primarily from the largely non-ascriptive and economic core of class conflict. Ethnic conflict may have an economic basis, but that is not its defining feature. The politics of ethnic group can be defined irrespective of internal class differentiation, race, language, sect or religion. So communal and ethnic mean the same.
