Tardigrade Admin · Accepted Answer

Birds show ZZ-ZW type of sex determination, where male birds are homogametic (ZZ) and female birds are heterogametic (ZW). Sex chromosomes of birds are represented by ZZ-ZW. Since the female is heterogametic, the sex of progeny is determined by the type of egg rather than the sperm.
