Which is the male genotype in the ZW sex chromosome sytem?
In the ZW sex chromosome system, the male genotype is typically represented as ZZ. In this system, females have a ZW genotype, while males possess two identical Z chromosomes, resulting in the ZZ configuration. This system is commonly found in birds, some reptiles, and certain insects.
Which male genotype in the ZW sex chromosome system?
In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.

What is a z chromosome?
A Z chromosome is a sex chromosome in a species in which the female is heterogametic (i.e. has different sex chromosomes). The counterpart is the W chromosome. In an XY system (e.g. humans), the male is heterogametic, XY, and the female is homogametic, XX. In a ZW system, the male is homogametic, ZZ, and the female is heterogametic, ZW. Examples of species with ZW systems include all birds, many reptiles, fishes and some insects.

Which pair of chromosomes produces a male off-springs?
It depends which species you are. There is the XY system (which mammals use) where it is the presence of the Y chromosome that induces male development. The Y chromosome contains genes like Sry that initiate the male developmental program. Male mammals have an X and a Y chromosome, female mammals have two X chromosomes. However, for other species, like birds, use the so-called ZW sex chromosome system where it is actually the absence of the W chromosome that permits male development - male birds have two Z chromosomes and female birds have a W and a Z chromosome. And then there's the X0 system, which many insects use, where two copies of an X chromosome results in a female but a single copy of an X chromosome results in a male.
What is the genotype of a male and female?
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male.Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
What is the role of chicken sex chromosomes in determining the gender of chickens?
The role of chicken sex chromosomes in determining the gender of chickens is similar to that in humans. Female chickens have two Z chromosomes (ZW) and male chickens have one Z and one W chromosome. The presence of the W chromosome determines the chicken's gender as female, while its absence results in a male chicken.
Do chromosomes determine the sex of a penguin?
Yes, as in all birds, the penguin's sex is determined by it's chromosomes. But interestingly the bird system is different from the one in mammals (including humans). Humans are female when they have two X chromosomes (and male if they have both X and Y), whereas two Z chromosomes make a bird a male (and females have both a Z and W chromosome).
When was .zw created?
.zw was created in 1991.
