Genetic Implications and Disease Predictions

BIOCHM-QKKHEL

The genetic makeup of an offspring is a cocktail of its parents' genetic materials.

Genetically-based diseases and disorders are tied to somatic (the 22 non-XY) or sex (X/Y) chromosomes. The schematic below showcases a disease pedigree for a dominant X-linked disease (so any carrier of a 'red' X chromosome is affected by the disease).

What are the probabilities that each offspring of M1 and F1 would be affected by the disease?

A

All offspring would have a 50% chance of being affected by the disease.

B

The male offspring will always be affected by the disease, while the female offspring have a 50% chance of being affected.

C

The female offspring will always be affected by the disease, while the male offspring have a 50% chance of being affected.

D

None of the above.
