Answer:
Hormones
Explanation:
Hormones is the term used for chemical secretion of endocrine glands responsible for changes taking in the body.
Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.
Best answer is A.
100........................don't mind the dots
Heterozygotes make up 20% of the population.Homozygotes make up 80% of the population.In the entire cat population, 60% of the alleles are TS.In the entire cat population, the frequency of the TL allele is 0.4.Assuming random mating, each gamete has a 40% chance of having a TL allele and a 60% chance of having a TS allele.
The gene pool for tail length in the population is composed of alleles TL and Alleles TS .The allele frequency of TL is 0.4 (160/400). Another way to express this is that 40% of the alleles are TL .The allele frequency of Ts is 0.6 (240/400). Another way to express this is that 60% of the alleles are Ts .Therefore, each of the gamete either the sperm or the egg has a 40% chance of carrying allele TL and a 60% chance of carrying allele Ts, assuming mating is random.
