Are males or females more likely to have a sex linked trait?
Males are more likely to have a sex linked trait
Why does the Y chromosome not carries genetic information?
The Y chromosome is too short to hold genetic information

Polygenetic
Epistais
What does dominance hierarchy mean?
Dominance hierarchy refers to a certain trait being dominant over all other traits
What is pleiotrophy?
Pleiotropy is when 1 gene expresses multiple traits
What is polygenic?
Polygenic is when 1 trait is expressed by 1 or more alleles
What is epistais?
Epistais is when 1 gene controls the expression of 1 or more traits
