Okay, the question asks, in humans, some of the traits, for example, height, or skin color, or hair, they may vary widely.
00:12
And what is this inheritance pattern? and the correct answer should be a polygenic inheritance, because these traits are controlled by many genes.
00:23
So poly means many and genic means gene.
00:27
So that's why the correct answer is a, because most of the traits.
00:31
Multiple genes contribute to these phenotypes.
00:34
And then i'm going to explain why b, c, d are incorrect.
00:38
So for b, it's incomplete dominance.
00:40
What it means is that if you have a gene and two alleles, neither of the allele is either dominant or recessive...
