Answer:
The incorrectly matched pair is
Sex influenced trait - Milk glands in female.
Explanation:
Milk glands in females are a sex-limited trait since it is expressed only in females due to the sex hormones ( progesterone)
Sex Influenced trait is the one that is influenced by sex. If the male has one recessive allele, he would show that trait. However, a female would show that trait only when there are two recessive alleles.
example- Short index finger in male
The limited trait is when a trait can be expressed in only one sex. eg. the presence of a beard can be expressed only in males.
Holandric trait- these traits can be expressed only by genes that are present on the y chromosome.
These are only inherited to a man from a man.
Example- Hypertrichosis.
