Answer:
c) expression of genes and production of specific proteins.
Explanation:
Estrogen is a lipid-soluble steroid hormone that diffuses through the lipid bilayer of the plasma membrane of its target cell. The hormone binds to its nuclear receptor and receptor-hormone complex then alters the expression of particular genes.
It triggers transcription of specific DNA sequences into mRNA which in turn enters the cytoplasm and serves as a template for synthesis of specific proteins.
Estrogen is the female sex hormone and stimulates development of secondary sexual characters in females as well as required for maturation of egg.

As female has XX chromosome so they can be carrier if one chromosome is recessive to the disease and have muscular distrpphy if female has homozygous condition for the disease !!
But in male ; which has only one X chromosome i.e XY , it can not be a carrier !! Male even if has the recessive gene but due to having only one X gene will get muscular distrophy.
I hope now you understand; if got any problem ; comment !!
