If someone with auburn hair has children with someone with red hair (but whose mother had black hair ) what are the genotype and
tensa zangetsu [6.8K]

The phenotype is - 75 % red and 25 %brown.

The genotype is hRhR - 25%

hBkhR - 50%

hBrhBk - 25%.

<h3><u>Explanation:</u></h3>

The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.

Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be

Father - hBr and hR

Mother - hBk and hR

So, the probable combinations are hBrhBk, hBrhR and hBkhR.

The frequency of the combinations are 25%, 25% and 50% respectively.

The phenotypic ratio will be red : brown as 3:1.

Shalnov [3]

True

Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.

Explanation:

The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of  several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.
