Herencia (segunda parte)

The video tutorial explains how cells determine which gene versions, or alleles, to express. It covers the difference between dominant and recessive alleles, using eye color as an example. Diseases caused by recessive alleles, like cystic fibrosis, and those caused by dominant alleles, like Huntington's disease, are discussed. The video also highlights that most traits are influenced by multiple genes and environmental factors.

What is the probability of a child inheriting Huntington's disease if one parent is a carrier?

Discuss the role of multiple genes in determining diseases and characteristics.
