Chromosomes

Sex cells (better known as gametes) being product of meiosis have single set (haploid number) of chromosomes whereas body cells have diploid number. Thus, 22 pairs of autosomes and one pair of sex chromosomes (XY), thus 46 chromosomes are present in our body cells. The gametes (sex cells) contain only 23 chromosomes in each.

A gamete can possess n+1 or n-1 chromosomes as a result of nondisjunction.

Species have homologous chromosomes because these pairs consist of one chromosome inherited from each parent, ensuring genetic diversity and stability during reproduction. Homologous chromosomes carry genes for the same traits, although they may have different alleles. This arrangement allows for the proper segregation of genetic material during meiosis, facilitating the formation of gametes, and contributes to the evolutionary adaptability of the species.

In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.

Whether someone is a female or male.

Hemophilia itself is really just a genetic disorder. It causes problems with blood coagulation and people with the disorder tend to bleed a lot if cut, hence the name "bleeders." The disorder is caused by a mutation in the factor VIII gene, leading to a deficiency in factor VIII. (Factor VIII is a protein that is associated with blood clotting.) The deficiency in the blood clotting factor causes the affected person's blood to clot improperly. The factor VIII gene is located on the X-chromosome and is transmitted by recessive inheritance. Males have an X-chromosome and and a Y-chromosome and females have two X-chromosomes. This means that females would only carry one of the mutant alleles for hemophilia and are said to be carriers. Females are usually found to be only carriers and rarely express hemophilia. Males, on the other hand, will receive one X-chromosome from their mother and a Y-chromosome from their father, leading to hemophilia.

Selected Answer: The father donated one of each pair of homologous chromosomes, and the mother donated the other.

The average human has 24 chromosomes, and autistic people have two copies of the 23rd in place of the 24th

Color blindness is typically linked to the X chromosome. The most common form, red-green color blindness, usually affects males more than females because they have only one X chromosome. If a male inherits a faulty gene for color vision on his X chromosome, he will likely experience color blindness.

They get Klinefelter syndrome. They have male sex organs, but the testes are abnormally small and the man is sterile. Even though the extra X is inactivated, some breast enlargement and other female body characteristics are common.

Each parent contributes 23 to each offspring. 23+23=46.

It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.

After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.

The prophase phase is when DNA winds up into chromosomes. It winds up to remain organized. Cytokinesis is when the DNA unwinds again.

Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.

The term is monosomy, in which one chromosome of a pair is missing. Turner's Syndrome is an example of monosomy, in which there is only one sex chromosome, which is the X chromosome. Humans with Turner's Syndrome are female, but sterile. The genotype of the sex chromosomes in Turner's Syndrome is XO, in which O represents a missing chromosome.

The Y chromosome is found in males only. Females have XX chromosomes whereas males have XY chromosomes. That is why they are different, because an XY cannot be female and an XX cannot be male.

It doesn't.

It's all about what's inside those chromosomes (DNA). Potatoes have 48 chromosomes, humans have 46 and fruit flies have 8.

they are lethal and cause spontaneous abortion of the embryo early in development.

If a cat has 19 pairs of chromosomes, each gamete will have 19 single (not pairs) of chromosomes.

Chromosome is a condensed form of the DNA, not an organism. Therefore, it doesn't fit into either of the categories because it is not an organism to begin with. However, a chromosome is only found in a eukaryote because the formation and the split of a chromosome is part of mitosis, a division of the nucleus.
