What is a z chromosome?
The Z chromosome is a sex chromosome found in birds, reptiles, and insects. In species with ZW sex determination, females have two Z chromosomes (ZZ) and males have one Z chromosome (ZW). The Z chromosome plays a role in determining the sex of an individual.
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.
How many chromosome are present in the antherozoid?
It depends upon the species to which antherozoid belongs .

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 .
How many chromosome are present in the antherozoid?
It depends upon the species to which antherozoid belongs .
How many chromosomes does a female grasshopper have?
Grasshoppers have 3 ocelli.
How many chromosomes are common to both males and females?
23 chromosome pairs in BOTH male and female.
In plants and animals an offspring inherits How Many genes?
The number of genes and number of chromosomes inherited depend on the species. The number of chromosomes a species has is known as the chromosome number. For example, (disregarding polyploidy or polysomy) a human baby has 46 chromosomes, but a horse has 64. Chromosomes usually occur as one of a pair in humans, and so they have 23 pairs of chromosomes. However, it is common in plants to have many sets of chromosomes and so they do not occur in pairs, but in triplets, or as sets of 4, 5 or 6 etc. Some species of strawberries have 7 of each chromosome. The number of genes depends on how long the chromosome is, and each chromosome in each different species will have a different number of genes on the chromosome.
