The team had hypothesized that this type of organisms will be good candidates for production of bio fuels. The group concentrated on working with algae; these were grown under different conditions and their lipid contents were assessed. Their work has led to identification of many algae species as potential sources of bio fuel. <span /><span>

Why is freckles not X linked dominant trait
forsale [732]

Answer:

The presence of freckles in a individual, or predisposition to have them, is a trait that is inherited with an autosomal dominant pattern, and is not related to sex-linked inheritance.

Explanation:

Freckles are accumulations of melanin in the skin, which form small reddish or light brown spots, predominantly in white-skinned people.

<u> The melanocortin receptor gene</u> undergoes a change that gives rise to a variant - which is phenotypically expressed in the presence of freckles - whose inheritance has been determined to be autosomal dominant.

<u>Under no circumstances is the transmission of the gene that determines the presence of freckles linked to sex</u>, because is an autosomal trait, as is hair, eye or skin color.

Describe the digestive process?
babunello [35]

Explanation:

Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.

Why don’t recessive traits always eventually disappear from populations?
Iteru [2.4K]
Because the recessive trait might not show, but its there, lets say B is brown eyes and b is blue eyes, BB is brown, Bb is brown, and bb is blue, if B is present, brown will always show, but as long as the little b is there, there is a chance of the kids having blue eyes, sure most people would have brown eyes, but a lot of the people with brown eyes would be Bb
