In order to answer this question, let's talk about inheritance.
00:02
It says match each type of inheritance with its definition.
00:07
We have incomplete dominance, polygenic inheritance, sex link, trade, complete dominance, codominance, and pliotropia.
00:14
So we have here, dominant alleles are always present in the phenotype, and excessive alleles are not present in the phenotype if a dominant aline is present.
00:23
And this is for complete dominance.
00:26
Let's just label like this, okay? like this.
00:31
And why will be causing complete dominance you're going to have a dominant and aggressive allele.
00:35
When you have the homocylus dominant or the heterozygose, it means whenever the dominant allele, even when you have only one dominant allele present, you're going to express the dominant phenotype.
00:45
And when you have only two excessive alleles, it means when you have zero dominant alils, you're going to express the excessive allele.
00:52
So this is complete dominance.
00:54
Okay.
00:55
The second statement says multiple genes combine their effects to produce a single phenotype.
01:01
And this is for polygenic inheritance.
01:05
Polygenic inheritance is practically, or practically says that the inheritance of a trait is governed by more than one gene.
01:13
Okay? so in this case, for example, many genes are going to call for a color, not only one gene, like in this case, for example.
01:20
So this is the answer for, second statement, then you have the third statement that says, a single gene produces multiple effects and phenotypes.
01:32
And this is going to go for playotropy.
01:38
Preyotropy refers to the phenomenon in which a single locus, for example in this case, this locus here, the a gene, okay, affects two or more apparently angrily related phenotypic traits, okay, or, well, or phenotypes, okay? and it's often identified as a single mutation that affect two or more wild type traits.
01:57
For example, maybe a mutation in this gene from cause brain tumors and also bladder tumors or genital tumors or maybe skin changes.
02:09
So many phenotypically different traits, okay? so this is pleiotropic...
