zloy xaker [14]

Answer:

The percent chance that the offspring will have a single comb is 25 %

Explanation:

Given,

The allele for single comb represented as "a" is recessive to the allele for pea comb represented as "A"

Genotype of male - Aa

Genotype of female - Aa

Gamete of Male - A, a

Gamete of female - A, a

Cross between Aa and Aa will produce

AA, Aa, Aa, aa

Thus, out of four offspring only one has "aa" genotype and hence this individual will express the recessive trait i,e  aa

The percent chance that the offspring will have a single comb is

\frac{1}{4} * 100\\

25 %

Ilya [14]

Explanation:

Seretonin is a hormone that is synthesized from the hydroxylation of amino acid tryptophan resulting in the formation of 5-hydroxytryptophan which further undergo de carboxylation to form seretonin.

 Seretonin is found in both myentric neuron and seretogenic neuron.Seretonin helps to control mood,desire for food and sleep.

  Selective seretonin reuptake inhibitors are used as antidepressent that interfere with the re absorption of seretonin thereby maintaining high level of seretonin in the synapse.
