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

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.

Why do humans have a strong impact on the fast carbon cycle?

dusya [7]

Burning fossil fuels or cement has relatively little of an influence on humans in terms of producing carbon dioxide. The general people has been duped into believing we are a major factor in the greenhouse effect.

The biggest misconception regarding the movement for people to emit no net amount of CO2 is that natural supplies of this plant nourishment dwarf our emissions. This indicates that even if all people disappeared overnight, atmospheric CO2 levels would not significantly drop.

The statistics on the steady increase in CO2 throughout the heaviest periods of the global lockdown, which significantly restricted any human-sourced emissions, will give you a decent idea of this.

As for the so-called greenhouse gases, CO2 naturally occurs in water vapor, which makes up more than three times as much of the GHG as CO2. This indicates that the human component of the GHG is 0.6 percent.

When you take into account how little human emissions are in the grand scheme of things, you have to stop and wonder if any efforts you make to lower your emissions are in vain.

Thank you,

Eddie
