Here are the answers :)
Q24) In cattle for instance, lactation is expressed in females but never in males. Both male and female however possess a gene pair for lactation.

Q25) The GR(genotypic ratio) is 100% non-bald for the PR: 50% or 1/2 [tex] X^{B} X^{b} [/tex] or (female non-bald) and 50% or 1/2 [tex] X^{B} Y^{b} [/tex] or (male non-bald )
(see the attachment)

Q26) Sex-Influenced Traits & Sex-limited traits are both autosomal.  Autosomal, meaning that their genes are not carried on the sex chromosomes. ( X or Y)
Q27 The main difference between the two is that the sex-influenced is a trait that is more dominant in a certain sex and it takes two recessive genes on part of the less dominant sex for it to appear on the other hand,  sex-limited is a trait that is in both male and female but shows up only in one gender.

Hope this helps! :))
