Considering people who suffer from diabetes can have issues and need help with circumventing the difficulties this disease can pose for them, it's very possible that other people (who are part of the support structure/inner social group of the person who's suffering from it) would need to help him or her with his diabetes issues.
This answer explains how other people might be affected by someone having diabetes in their particular social group. I hope this was what you were interested in, your question seemed to ask this.
A- the antlers and horns are structural adaptations. The fighting is a behavioral adaptation.
Antlers and horns are physical adaptations that some mammals have acquired over time. However, fighting is not a physical feature but a behavioral adaptation used to beat other males during mating season.
Genotype frequency: RR is dominant, Rr is heterozygous and rr is recessive.
R^2+2Rr+r^2 = 1
R = 0.85
R^2= 0.85*0.85 = 0.7225
<span>Genetic variation can be caused by mutation (which can
create entirely new alleles in a population), random mating, random
fertilization, and recombination between homologous chromosomes during
meiosis (which reshuffles alleles within an organism's offspring)</span>
