Why does the Y chromosome be unlikely to contain any of the genes that are absolutely necessary for survival?
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.
Examine the chromosomes labeled x and y how does these two chromosomes compare?
Chromosomes X and Y do not truly make up a homologous pair. They act similarly in their roles, but they are not homologous (the same). The X chromosome in humans is much longer than the Y chromosome and also contains many more genes.
How can you tell if a genetic disorder in a pedigree chart is sex linked?
In humans (and other animals with the XX/XY sex chromosome configuration) a sex linked trait will show up in sons 50% of the time and 0% of the time in daughters of a female carrier.The only way that a female can have the necessary phenotype/genotype to display the trait is for thefather to be affected and the mother to be a carrier or affected herself.
What are two exact copies of DNA that makes up each chromosome?
the answer is chromotids
Explain mechanism of sex determination in humans?
In humans, sex determination is based on the presence or absence of the Y chromosome. If the individual has a Y chromosome, they will develop into a male (XY). If they do not have a Y chromosome, they will develop into a female (XX). Key genes on the Y chromosome, such as the SRY gene, trigger the development of male characteristics.
What do the genetic codes xx and xy mean?
There are 22 autosomal chromosomes and 2 sex chromosomes in humans. In all the other chromosomes, the homologous pairs match up genetic loci. However, in human sex chromosomes the X and Y chromosome are different (with the X chromosome being much larger and the Y chromosome carrying genes that cause "maleness"). Someone with an X and a Y chromosome is a male because he has a Y chromosome that carries the genes that code for "maleness". Females "lack" this Y chromosome, and thus show characteristic female phenotypes.
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
Contrast the sex chromosomes found in a human females and human males?
the female egg cell is almost like a body cell the sperm cell however has 3 sections. A tail for moving, a mid section full of energy producing mitochondria, and a head containing the nucleus and covered with enzymes.
Why is your dads sperm responsible for the sex of the child?
Because the child's sex is determined by a pair of chromosomes, called X and Y. Each parent contributes one of the chromosomes. Females have nothing but X's, so they can contribute only an X. Males have an X and a Y. The male can contribute either one; it's a toss-up. If the male contributes an X, the result is XX, a girl. If the male contributes a Y, the result is XY, a boy.
What makes up each chromosome?
A centromere and sister chromatids.
What is the threadlike material that makes up a chromosome?
red a book

What kind of cell make up your finger?
The chromosome is what makes up your finger.
Why do more males end up with sex-linked disorders?
More males than females end up with sex-linked disorders because of the y chromosome. It is shorter than the x-chromosome, and increases susceptibility to these problems.
Why males are afflicted with hemophilia more than females?
Because males have the chromosome XY. And Hemophilia attacks the X chromosomes, so if the disorder gets to the X chromosome of the male, it doesnt have another X chromosome to back it up like females do.(XX)
