if a blue eyed offspring is formed from black eyes parents, what type of character is the blue eye dominant or recessive? expalin with the help of a chart

The study of a living being is called biology.

The correct answer is recessive genes or mutation.

The character in the living organism is due to the gene present in the body. The genes are present in a pair. The single gene is known as an allele. The two alleles are as follows:-

In this question, the parents have a black color eye but the offspring has blue color eyes. This is due to recessive gene inheritance because this gene is dormant in their parent and shows its character in this generation.

The chances of this case are 1/4 out of total.

The mutation is also the reason for the blue eyes because the abnormal change beside the population is called a mutation.

Hence, the correct answer is Recessive and mutation.

If a blue-eyed offspring forms from black-eyed parents, the blue-eyed trait must be recessive.

Explanation:

The blue-eyed trait is the recessive one because otherwise it could not come from parents with black eyes. A recessive trait is only expressed when both alleles for that trait are the same, and can only come from parents with the same trait, or heterozygotes.

In this case, both parents must be heterozygous, i.e. carriers of the recessive allele. If black eyes is B and blue eyes is b, then the genotype of the parents would be:

In a Punnett square can be seen the crossing:

Bb X Bb

Alleles    B     b

B           BB    Bb

b           Bb    bb

Where the offspring could be:

Therefore, if blue eyes is the recessive trait, as if it were the dominant trait it could not be the product of black-eyed parents.
