Yes, although it has less DNA and is smaller than its partner the X chromosome
Yes. Boys have one X chromosome and one Y chromosome. Yes; the genotype for males is XY and for females is XX.

From smallest to largest: DNA (where DNA = short sequences of nucleotides) gene chromosome nucleus sperm cell
The Y Chromosome.
Chromatin. The proteins are histones, used to organize and compact the DNA.
The SRY gene is a gene on the Y chromosome required for the development of testes. It stands for Sex determining Region on Y chromosome.
autosomal dna, X chromosome, Y chromosome,and mitochondrial
The DNA of the Y-chromosome is the DNA that is transmitted only from father to son. This is because women have two X-chromosomes, one of which is given to each child. But men have one X-chromosome and one Y-chromosome. So if a father gives a Y-chromosome to his child that child will be male, while only females receive the father's X-chromosome.
every and any DNA strand can constitue to a chromosome :)
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
The Y chromosome contains more than 59 million blocks of DNA and represents almost 2% of the total DNA in cells within the body. The Y chromosome contains between 20,000 to 25,000 genes within the human genetic make-up.
The Y chromosome will be included in the DNA test that determines paternity, because as we all know, half of our DNA comes from the mother and the other half from the father, which makes up the full genetic profile of the child with both x and y chromosome pairings.
Well, you only have two choices or examples: X and Y.
Yes, the y chromosome is critical for survival, for males at least. It contains the DNA (or genes) for the genetic make up of a male's body. No, I don't think so because Y chromosomes just dermine the sex. If it was critical to life then no girl would be alive because they don't have Y chromose. Y chromosome truly determines sex. It contains SRY gene that produces TDF which makes sth to male. it not important for survival, just for prodactivity, since Y has came from X chromosome.
This varies by species but in humans the female gender has cells with two x chromosomes of which one is randomly inactivated. This inactivated chromosome is referred to as the barr body. The male gender has cells with both an x chromosome and a small y chromosome. Source - Any recent biology textbook.
the y chromosome doesn't carry any genetic information
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
