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.
What is female peguin called?
I'm reasonably sure it's a hen, and males are cocks. (Don't snicker, even if you are a disgruntled female.) This is the correct nomenclature for game and domestic fowl, and I think it carries over to all birds. Otherwise, you could refer to them as "ZW penguins", after their heterogametic chromosome makeup (unlike most , but not all, species, in which the male is the heterogametic sex), or simply "the female". If the latter is good enough for David Attenborough, it's good enough for me.

Why are human females homogametic?
Human females are homogametic because they have two X chromosomes (XX), making them the heterogametic sex, while males have one X and one Y chromosome (XY). This is in contrast to species where males are homogametic and females are heterogametic, such as birds.
How do birds get chicks?
Male and female have sex. Female lays egg(s). Eggs hatch = Chicks
What sex parakeet should get to get along with a 2 yr old male?
The sex of the bird does not effect how well the birds will get along. Although, If you do have a female with a male, there is a possibility of the birds mating.
Why is it believed that the father determines the sex of his children?
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.
What are the differences in reproductive strategies between the heterogametic sex and the homogametic sex in various species?
In many species, the heterogametic sex (typically males) produces different types of sex cells (sperm) while the homogametic sex (typically females) produces only one type of sex cell (egg). This difference in sex cell production leads to different reproductive strategies, with males typically producing many small, mobile sperm to increase the chances of fertilization, while females produce fewer, larger, and less mobile eggs. This difference in reproductive strategies is known as anisogamy.
What is the sex chromosomes of male?
In humans and other mammals, a male has XY sex chromosomes. In birds, a male has XX chromosomes. In amphibians, male chromosomes look the same as female chromosomes.
Why male is called heterogametic?
Male is called heterogametic because they produce two different types of gametes (sperm), carrying either an X or a Y chromosome. In humans, males are XY, which means they determine the sex of the offspring. On the other hand, females are homogametic, as they produce only one type of gamete (eggs) carrying an X chromosome.
Many chromosomes do parrots have?
a parrot has 24 chromosomes
How do flowers have babies?
The pollen from the male sex organ has to get into the female sex organ called the pistol. Sometimes the wind does this. Sometimes insects, birds or bats do this. Sometimes humans help plants produce seeds.
