sex chromosomes
Special chromosomes called sex chromosomes determine the sex of most animals. These chromosomes are designated as X and Y in humans, with females having two X chromosomes (XX) and males having one X and one Y chromosome (XY).
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
They measure it with a special instrument called seismograph.
chordates
The number of chromosomes is determined by counting the paired structures called sister chromatids during cell division. Each sister chromatid contains a copy of the genetic material, allowing for accurate distribution of genetic material to daughter cells.
Pairs Of Chromosomes Are Called :Sets
It is called a male gecko. There really is no special name for it, nor do special males hold a special position like some other animals do.
Chromosomes that look like X's are called "homologous chromosomes."
Organisms with three or more sets of chromosomes are called polyploids. This can occur in plants and some animals, where multiple sets of chromosomes are present in each cell. Polyploidy can result from errors in cell division or hybridization between different species.
Answer:chromatin not chromosomes. :DIt Is Chromosomes Not Chromatin:]
When two animals fight for something, it doesn't have a special name. It's just called two animals fighting over something.
The genes carried on the X and Y chromosomes are called your "sex chromosomes".
