1. which of the following is true about polygenic inheritance?

o it produces characters that vary in the population along a continuum
o it is never seen in human beings.
o it produces only heterozygous individuals
o it produces only homozygous individuals

Explanation:

Polygene inheritance involves multiple genes influencing a single trait. This leads to a wide range of phenotypic variations in a population, forming a continuous distribution (a continuum). For example, human height is a polygenic trait with a wide range of values in the population. It is seen in humans (like height, skin color). It does not produce only heterozygous or homozygous individuals as the combination of multiple genes (from different parents with various genotypes) can lead to different zygosity combinations in offspring.

Answer:

It produces characters that vary in the population along a continuum.
