WebAn autosome is any chromosome that is not a sex chromosome. [1] The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal ( sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. [2] WebIn this system, females have a pair of dissimilar ZW chromosomes, and males have two similar ZZ chromosomes . In contrast to the XY sex-determination system and the X0 sex-determination system, where the sperm determines the sex, in the ZW system, the ovum determines the sex of the offspring.
