Non-mendelian genetics

2

What number in the blood group is MNS?

4q31.21

Position 31.21 of the long arm of chromosome 4, what is the code?

No

In the MNS blood group in breeding 2 F1 Parents, Is the Mendelian F2 phenotype still the same?

Codominance

Both alleles are expressed simultaneously and equally in the progeny

1

What number in the blood group is ABO?

M,N,S,s,U

Based on the antigen present on the surface of MNS, what are those antigens?

A,B

Based on the antigen present on the surface of ABO, what are those antigens?

A

Whatever blood type you may have that is also your antigen, for example if you are blood type A, your antigen is ?

No

Does blood type O have antigen?

4q31.21

Where MNS gene located?

9q34.2

Where ABO gene located?

Glucose

First sugar that will attach to ceramide?

Fucose

What sugar will attach to the terminal galactose?

A

H antigen + GalNAc, what blood type?

B

H antigen + Gal, what blood type?

A,B

H antigen + GalNAc + Gal, what blood type?

O

H antigen + None, what blood type ?

Multiple allele inheritance

Three alternative alleles of one gene exist

Multiple allele inheritance, codominant

The ABO blood group system exhibits?

SRY gene

codes for a protein that activates other genes for male development

Males

are more likely to be affected by a sex-linked d/o than females since males only have one copy of the X chr

X-linked inheritance

traits controlled by the genes located at the X chromosome

Pedigree analysis

establishes the mode of inheritance of a particular trait or disease throughout a family
