What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
How do you know if a trait is sex linked dominant or sex linked recessive?
A trait is sex-linked dominant if it appears in every generation and affects both males and females. It is sex-linked recessive if it skips generations, more common in males, and passed from carrier females to affected males. Mendelian inheritance patterns can help determine if a trait is sex-linked dominant or sex-linked recessive.
Is Colourblindness in males is an example of incomplete dominance?
No, it is an example of sex-linked recessive inheritance.
Is pku sex linked recessive or sex dominant?
I think I read somewhere that there are some variants of it that are recessive and others that are dominant.
What are the names of some genetic inheritance patterns?
Some common genetic inheritance patterns include autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. These patterns describe how traits are passed down from parents to offspring.

Sex-linked.
How might a scientist determine whether a trait is sex linked by observing the offspring of several genetic crosses?
By observing the proportion of affected offspring and whether males or females are more affected.
What are the four genetic forms of cutis laxa?
