What are the genotypes?

Postby mensamedlem » Sat Nov 21, 2009 9:23 am

What are the genotypes for each individual if the trait is set to be x-linked recessive?

Green = healthy. Yellow = sick.

II. xX; XY; xX; XY; xY
III. xY

Cis or trans? That's what matters.

Is what I have written correct?

Figure 1: http://www.flickr.com/photos/44845730@N06/4121809554/

The inheritance is recessive because generations are skipped and because the sick children have healthy parents. It can be autosomal because the children of a diseased and a normal parent are carriers. They will thus have a bad gene from the ill parent and a good gene from the healthy. There may also be that it is x-linked because an affected father not disclose his illness to his son. Boys always get their single X chromosome from their mother and thus can not inherit his father's bad gene.
