		They are encoded in the female sex chromosome (X)
		They are associated to sexual behaviors
		They are always dominant.

Answer 1

1) the flies mate in the chamber of set of temperature

Explanation : here in the incubation chamber the favourable conditions provided for breeding process especially the optimum temperature(warm) for reproduction and hatching.

2)correct statement regarding sex linked traits

They are encoded on the male sex chromosome

They are encoded on the female sex chromosome

Explanation : both are correct, the sex linked genes means the genes found on either of sex chromosomes, they are not always dominant but posses both allies, and they are not necessarily associated with sexual behaviour's.
