If a female of this species has one chromosome 12 with a blue gene and another with an orange gene, she will produce two types of eggs. Half of her eggs will carry the blue gene, while the other half will carry the orange gene. This genetic variation can lead to offspring with either blue or orange traits, depending on the combination of genes inherited from both parents.
Yes
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.

In humans, which sex chromosome determines if an offspring is a male or female?
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.

If you are breeding Plusle and Minun, a female Plusle with a male Minun will produce a Plusle and a female Minun with a male Plusle will produce a Minun. Every female Pokemon will produce her species.
In humans, the sex of an individual is determined by what combination of sex chromsomes he or she possesses. The sex chromsomes are called 'X' and 'Y' (because of their shape). Females possess two copies of the X chromosome, while males have one X and one Y. In more technical language, in humans the female is the homogametic sex and the male is the heterogameticsex. These terms give a clue to the answer to your question. Females can only produce one type of egg, those with an X chromosome, since they only have one type of sex chromosome (the X) to work with. Males, on the other hand, can produce two kinds of sperm: those carrying an X chromosome, and those carrying a Y. Since every human--male or female--carries at least one X chromosome, and the female can only produce gametes with X chromosomes, the male determines the sex of the child, because if he contributes another X chromosome, the child will be female, and if he contributres a Y, the child will be male. Note: in some other organisms, such as birds, the situation is reversed: the female is the heterogametic sex, and the male the homogametic sex. So in birds, the female determines the sex of the offspring.
Unlike other species, female jicama does not need a male plant to produce fruit.
In humans, which sex chromosome determines if an offspring is a male or female?
Calico cats are almost always female. This occurs because the gene that determines color is located in the X chromosome and two X chromosome produce females.

No, a W chromosome in bird species represents one of the sex chromosomes, which determines the female sex. It does not physically resemble the letter "W." The W chromosome carries genes that are essential for female development and reproduction.
2 female Bettas can not produce young. I guess it is possible that two females could go through the mating processes but I have never known it to happen with Anabantids of any species.
