Why human with heterozygous genotype will have the dominant phenotype?

1 answer:

5 0

A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.

Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.

Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way.

It is only possible to answer your questions in a specific way by reading the experiment, however, I can inform you that formites are objects that allow the colonization and growth of microorganisms that can be major causes of diseases. Among these microorganisms are bacteria, fungi and viruses of the most varied species. Among these microorganisms, both fungi and non-demanding bacteria can grow in a nutrient agar culture medium. This is because this is a very simple culture medium where bacteria that do not need specific nutrients can grow and where most fungi can grow too. However, it is impossible for viruses to grow in this type of culture medium or in any culture medium, since viruses only develop inside a host's organism. Bacteria known as fastidious would also not grow in this type of culture medium, since they only grow with the presence of very specific nutrients.
