What effect are multiple alleles likely to have on a population?

a. increase risk for genetic diseases
b. decrease risk for genetic diseases
c. increase phenotypic variation among a population
d. decrease phenotypic variation among a population

The right answer is C

An allele is a variable version of the same gene, because a gene can have several versions of the same gene, which can give slightly different structural proteins due to these variations in the DNA, thus, giving different phenotypes.

In most cases, the multiplicity of alleles in a gene gives phenotypic variation in the population due to their different expression.  Therefore, the larger the number of alleles, the greater the number of phenotypes in the population.

To a lesser extent (more rarely), some variation can be a deletion giving non-functional proteins, causing rare diseases (like cystic fibrosis, hemophilia, sickle cell anemia).

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
