Chromosomes

the cytoplasm

Chromosomes are primarily made from DNA (deoxyribonucleic acid), which is a long molecule that carries genetic information. In addition to DNA, chromosomes contain proteins called histones, which help package and organize the DNA into a compact structure. This combination of DNA and proteins allows chromosomes to fit within the cell nucleus while regulating gene expression and DNA replication.

Most zygotes with serious chromosomal problems are born with severe mental and physical disabilities; many die before being born or shortly thereafter.

Women have two of them.

An allele is essentially the same as a gene so there is no difference in quantity between the two in any cell. Gene is a more common general reference to genetic material at a particular locus whereas allele often refers to an example of variation at a gene locus. For example the allele for tall (T)

According to mendel's law of segregation, what happens to chromosomes during meiosis is that, allele pairs do separate leaving each and every cell with a single allele for each trait.

Chromatin

It means they are female.

Yes, most plants and animals have chromosomes (although the # of chromosomes varies in different species) If you eat fruit, vegetables, grains, or meat you are eating chromosomes.

In humans there are 23 single chromosomes. In a zygote there are 23 pairs.

actually learn

Chromosomes are composed of two chromatids. Each chromatid is an exact replica of the other, and for this reason they're called sister chromatids. If the chromosome is an "X", then the left side is one chromatid and the right side is the other. Eventually the centromere will split in the middle of the "X" and the sister chromosomes will move towards the polar ends of the cell via kinetochore fibers.

Well... they can. In females (who contain XX chromosomes) there is a homologous pair of chromosomes. In males (XY) the Y chromosome must be in existence to activate the development of male characteristics... Otherwise they'd be females.

Prokaryotic Cell

Autosomes are the somatic chromosomes which control the body characters or somatic characters, Whereas Sex chromosomes are the allosomes which determines sex of an individual

The X chromosome is larger and carries more genetic information than the Y chromosome. The Y chromosome carries the genes that determine male sex characteristics, while the X chromosome carries genes that are important for both male and female development. Males typically have one X and one Y chromosome, while females have two X chromosomes.

This is a type of mutation called translocation.

TRUE

Whether or not a particular religion sees Jesus as divine or not, if he was human at all he had to have the XY chromosomes. One can assume that, if actually conceived by the Holy Ghost, the Holy Ghost has the ability to provide a Y chromosome...

XX for a girl and XY for a boy

1. As a storage of genetic information that will be passed down from parent to child that shape the nature and characteristics of the individual.

2. Plays an important role in the process of cell division.

3. Determining the sex of an individual.

A zygote is a fertilized egg cell, so it is diploid and thus has a full set of DNA.

If the adult has 30 pairs of chromosomes, the zygote would have 30 pairs. If there are 30 chromosomes, then the zygote will have 60 (30 from the mother and 30 from the father). It comes down to whether you meant individual chromosomes or pairs of chromosomes.

The homologus chromosomes form a four, quad, and in telephase the 'homologus' chromosomes separate in half. Then, they separate and make 2 diploid cells.
