A chromosome is a part of DNA that consists of a long arm and a short arm connected at the center called the Centromere.
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
Yes.
Chromosome
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.
In males, sperm contain only one sex chromosome. In females, eggs contain only one sex chromosome.
Well certainly a Y chromosome. XY is the sex chromosomes of males. In male gametes they would be n. That is some sperm would contain a X chromosome that a male would give to a daughter and other sperm would contain a Y chromosome destined for a son.
The two-rod structures that contain the cell's DNA is the chromosome.
Triploid.
