Answer:

The correct genotype would be-

mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.

Explanation:

Listing the genes in the way that they indicates the real combination of alleles is the genotype of individual.

Ability to roll your tongue is a dominant character which has a dominant and a recessive gene. Assume that the dominant allele ‘R’ is for the ability to rolling tongue and the recessive allele ‘r’ for unable to rolling our tongue. As we know mother can not roll her toungue she must have homozygous recessive alleles that means she has two copy of recessive allele. The father could posess any combination of these alleles: RR (homozygous dominant), or Rr(heterozygous dominant).

Thus, the correct genotype would be

mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.

The only people with Rh negative blood are people who have inherited two recessive alleles for this trait. But some people who a

zubka84 [21]

The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.

<h3>What are the blood type and Color-blindness inheritance patterns?</h3>

⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.

The allele Rh+ dominates over the allele Rh-.

Genotyopes and Phenotypes are as follows,

Individuals Rh+Rh+ express the possitive phenotype

Individuals Rh+Rh- express the possitive phenotype

Individuals Rh-Rh- express the negative phenotype.

To express Rh-, a person must inherit<u> two</u><u> recessive alleles</u> from their parents.

⇒ Color-blindness is an X-linked condition coded by a recessive allele.

As most sex-linked genes, it is transmitted together with the X chromosome.

The phenotype depends on the number of recessive alleles and the sex of the person.

Genotyopes and Phenotypes are as follows,

X⁺X⁺ women have normal sight.

X⁻X⁻ women are completely color-blinded

X⁺X⁻ women are partially color-blinded.

X⁺Y Men are not color-blinded

X⁻Y Men are color blinded.

In this case, only one recessive allele is enough to express the affection.

In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.
