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.
How many genes do cells obtain?
The number of genes varies from chromosome to chromosome and the number of chromosomes varies from species to species (from as few as 1 single chromosome per cell to as many 30,000 chromosome pairs per cell). Human cells have 23 chromosome pairs per cell.
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 female chromosome?
The X chromosome is one of the two sex-determiningchromosomes in many animal species, including mammals (the other is the Y chromosome). It is a part of the XY sex-determination system and X0 sex-determination system. The X chromosome was named for its unique properties by early researchers, and this resulted in its counterpart being named the Y chromosome for the next letter in the alphabet when it was discovered later.

A female grasshopper typically has 24 chromosomes.

If an egg cell contains 50 chromosome how many chromosome are in a sperm cell from the same species?
50

How many chromosome per cell does fish has?
It depends on the species.

What does XY mean?
In genetics, XY refers to the chromosomal pattern that typically determines male sex in many species, including humans. Males have one X and one Y chromosome, while females have two X chromosomes.
How many chromosome pairs are in a species with a haploid number of 68?
68 pairs .
What determines the sex of an organism-?
The sex chromosomes determine the sex of an organism. In humans, it is the 23 pair. Females pass on either or their X chromosomes, while males pass on either their X or their Y. If the male passes on their X chromosome, the resulting offspring is female. If they pass on their Y chromosome, the resulting offspring is male.
How many chromosomes does a jaguar have?
Jaguars have 38 chromosomes, which is the typical chromosome count for most cat species in the Felidae family.
Why does having only a single X chromosome make a person of necessity female?
Individuals with only one X chromosome (Turner syndrome) typically develop female characteristics because the presence of the X chromosome is required for the development of many female traits. A single X chromosome carries genes that play a key role in the development of female reproductive structures and secondary sexual characteristics, leading to a predominantly female phenotype.
How many chromosomes does a female grasshopper have?
A female grasshopper typically has 24 chromosomes.
