X-inactivation is necessary in individuals with two X chromosomes to ensure that only one X chromosome is active in each cell. This process helps to balance gene expression between the two X chromosomes and prevent an imbalance of gene dosage, which could lead to developmental abnormalities and disorders.
What else can I help you with?
What are the correct designation of the paired sex chromosomes?
the male chromosome is XY the female chromosome is XX
Which determines the sex of an organism?
The sex of an organism is determined by the combination of sex chromosomes they inherit. In humans, individuals with two X chromosomes are female, while individuals with one X and one Y chromosome are male. Other organisms may have different combinations of sex chromosomes that determine their sex.
A zygote is from a parent's 23 chromones each when reproducing?
A zygote is a cell that results from the union of two gametes, typically from different individuals. The zygote contains all of the genetic information necessary to form a new individual. This information is contained in the zygote's 23 chromosomes, which are a combination of the 23 chromosomes from each parent.
If a person inherits two X chromosomes that person will be?
If someone ends up with two x chromosomes (XX) Then they are a girl. If a person has one X chromosome and one Y chromosome(XY) then they are a boy. the men decide what sex the baby is since they have both an x and y. the women gives an x all the time.
Why is it necessary for the cell membrane to dissolve in mitosis?
The cell membrane needs to dissolve during mitosis to allow for the separation of duplicated chromosomes into two daughter cells. This dissolution is necessary to facilitate the process of cell division and ensure proper distribution of genetic material. Once the chromosomes have been successfully separated, the cell membrane reforms around each set of chromosomes to create two distinct daughter cells.
How similar are two people with respect to chromosomes genes and alleles?
Two individuals can be highly similar in terms of chromosomes, genes, and alleles if they are closely related, such as siblings. They will share a significant portion of their genetic material due to inheritance. However, unrelated individuals will have more differences in their genetic makeup, with variations in chromosomes, genes, and alleles.

What does it mean when a human has two X chromosomes?
When a human has two X chromosomes, it typically indicates that they are female, as females usually have two X chromosomes (XX) while males have one X and one Y chromosome (XY). This chromosomal configuration is associated with the development of female secondary sexual characteristics and reproductive systems. However, variations can occur, such as in individuals with Turner syndrome (a single X chromosome) or Androgen Insensitivity Syndrome, where individuals may have XY chromosomes but develop female characteristics.

What sex chromosomes do girls have?
the combination of sex chromosomes for a female is XXX it is the triple x because in 1947 a women in North Bonerville Africa found that women have 3 sex chromosomes while males only have two

Any species with a multiple set of chromosomes is?
Polyploid. This means they have more than two sets of chromosomes, which can result in increased genetic diversity and variations in traits among individuals. Examples of polyploid species include strawberries and wheat.
What are the two sex chromosomes that females inherit?
Females inherit two X chromosomes.
What do you mean by euploidy?
Euploidy refers to a cell or organism having a complete set(s) of chromosomes. It can be either haploid (having one set of chromosomes) or diploid (having two sets of chromosomes). Euploidy is seen in normal, healthy individuals.
If a organism has 2N8 how many chromosomes does it have?
it has two sets of chromosomes
