0:00 Hello.

00:01 So let's answer now the question.

00:02 So for number one, we are asked what type of inheritance pattern is hemophilia.

00:12 Okay.

00:13 So hemophilia is a condition that is located or found in the x chromosome of the person.

00:28 So it is found in the x chromosome and somehow it is a recessive condition.

00:34 Okay.

00:34 Now, which of the following here? is the pattern for hemophilia since it is found in the x chromosome so it is not pleotrophic because when we speak of a pleiotrothic inheritance pattern it is a gene that will have a multiple phenotype so that is not the point of hemophilia it is not also polygenic because this disease is not caused or this condition is not caused by many genes okay so it's not polygiene and it is not codominance because the condition hemophilia don't have two dominant alleles.

01:23 It can be, this condition is recessive, okay? it's not codominant.

01:31 So therefore, our answer here, since it is in the x chromosome, and since it is, a recessive condition therefore our answer here for number one is we have sex linked okay so it is sex linked because it is located in the x chromosome and it is recessive so our answer here hemophilia is a sex link recessive condition okay let's proceed to question number two so we are asked which of the following is the inaccurate, okay, inaccurate statement about blood types.

02:22 Okay, it is about blood types.

02:29 Okay, so we have here five options.

02:35 We have a, b, c, d, and e.

02:43 So option e states that when inherited together, a and b blood types exhibit codominated.

02:51 So this statement is correct.

02:53 So take note that a and b, they are codominance.

03:00 So allel a and allel b is or exhibit codominance.

03:10 Next we have here statement e.

03:12 It says here that this allele represents an antigen a, antigen a on the red blood cell.

03:28 This statement is also correct...
