How many chromatids have one chromosome?
Two (2). Before DNA replication, each chromosome is composed of a single chromatid. After replication, but before separation of the chromatids during anaphase, this is true.
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.
What is the amount of genes in an animal cell?
Genes and chromosome numbers vary from animal to animal
Who has the sex chromosome?
Every mammal (of any species, including human) have two sex chromosomes, which are either "X" or "Y". (These designations come from a vague approximation of the shape of the chromosome.) These exist in EVERY CELL in the animal. If the animal has two "X" chromosomes, the animal is female; if the animal has one "X" and one "Y" chromosome, the animal is male. In every species, the female only contributes an "X" chromosome to the offspring. It is the male contribution which might be either "X" or "Y", which will determine the gender of the child.
Does chromosome number indicate whether an organism is a plant or animal?
no

Why polytene and lampbrush chromosome has formed with the advent of evolution what may be the most probable reason?
well! Due to evolution..this type of giant chromosome came into picture...due to environmental changes and to adapt itself better with enviroment ..such change has been occured..such as high secreation in case of drosophila melanogaster...
Who discovered the x chromosome?
Hermann Henking

Is a chromosome an animal cell or plant cell?
A chromosome contains genetic material in both plant and animal cells.
How polytene chromosomes formed?
When DNA replication takes place without subsequent cell division, polytene chromosomes may result. These are giant chromosomes comprised of multiple chromatids (identical chromosome copies) arranged together like strands of a large cable. They are commonly found in the salivary glands of the fruit fly (Drosophila melanogaster) and are regions of active transcription.
Who discovered chromosome as a heredity bearer?
Gregor Mendel
What is the amount of genes in an animal cell?
Genes and chromosome numbers vary from animal to animal
Who discovered the chromosome?
I think it's Theador Schwann ..Not sure .....
Which type of the cells have chromosome?
Animal and plant cells.
How did the chromosome get its name?
When th chromosome was discovered, it was given that name for a reason. Translated from Greek to German, it was khromasoma. When translated to English, it means color body.
