Suppose you examined a pedigree of a large family, going back 6 generations. In generation 5, a woman ("G5W") has a serious gene
Westkost [7]

B: A mutation in one of G5W's parents, during gamete formation, created an X-linked dominant disease allele.

You need to analyze the sex gametes.

Boys are XY

Girls are XX

If you have an X-linked dominant disease you need only one affected X gamete to have the disease.

The mother has XX' where X' is de affected and reproduce with a healthy man XY and breed unhealthy boys, but because of the heterozygous gametes you could also have healthy ones XX and XY

Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
yarga [219]

Answer:

Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.

I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

I tried to explain it as best as I could I hope it helps!
