In order to answer this question, let's talk about genes.
00:06
In this case, it says adult hemoglobin is a multimeric protein with four polypeptides, two of which are alpha gloving and two of which are beta gloving.
00:17
So remember that the alpha gloving, the alpha gloving gene is found in the chromosome, in chromosome 16.
00:26
Okay, while the gene that goes for the beta -loving protein is found on chromosome 11.
00:42
And remember that a person has two copies of each chromosome.
00:46
So in this case, for example, if this is the person, you have or he has, or they have, okay, two chromosomes 16 and two chromosomes 11, like this.
01:00
So this question says, how many genes are needed to define the structure of the hemoglobin protein? so in this case, as you can see here, you only need two genes.
01:09
The alpha gene and the beta gene that are located in chromosome 16 and 11 respectively.
01:14
The next question says, if a person is heterocygo for wild type alleles, and alleles that would yield a minor as a substitution variance for both alpha and beta gloving, so you have particularly this...
