A human cell may have more or less than 46 chromosomes as a result of nondisjunction a process in what?
A human cell may have more or less than 46 chromosomes as a result of nondisjunction, which is a process that occurs during cell division where chromosomes fail to separate properly. This can lead to an incorrect number of chromosomes in the resulting daughter cells.
Human sex cells have 46 individual chromosomes?
Yes, except when there is an occurrence such as nondisjunction.
How can a human with 47 chromosomes be produced?
This occurs due to nondisjunction, in which one or more homologous pairs of chromosomes do not separate during anaphase I, or sister chromatids do not separate properly during anaphase II of meiosis. The resulting daughter cells (gametes) will have either 22 or 24 chromosomes. If the gamete with 22 chromosomes unites with a normal gamete with 23 chromosomes, the offspring will have 45 chromosomes (23 + 22). If the gamete with 24 chromosomes unites with a normal gamete, the offspring will have 47 chromosomes (23 + 24). These are usually lethal conditions.
How many chromosomes does a human cell that has been produced by the process of meiosis have?
After meiosis 2 in human cells are 23 chromosomes. Meiotic division occur only in reproductive cells because when spermatozoid and ovum combine they form again 46 chromosomes(23 pairs of chromosomes).
Is klinefelter's syndrome an inheritance?
It is a condition in which human males have an extra X chromosome. It is inherited when the extra X chromosome is retained because of a nondisjunction event during meiosis I (gametogenesis).
What combinition of sex chromosomes result in a male human being?
XY=male; XX=female…
What sex chromosomes do human females have?
XX is usual, XXX and X also result in a female.
How many dyads in chromosomes?
In human chromosomes, each pair of chromosomes consists of two homologous chromosomes, forming a dyad during the process of cell division. Humans typically have 23 pairs of chromosomes, resulting in 23 dyads. Therefore, there are 23 dyads in human chromosomes during the metaphase stage of meiosis or mitosis.
If a human liver cell divides by meiosis how many chromosomes do the new cell have?
If a human liver cell divides by meiosis, the new cells would each have the normal number of chromosomes for a human cell, which is 46 chromosomes. Meiosis is the process of cell division that results in halving the chromosome number to produce gametes (sperm and eggs) with 23 chromosomes each.
How many chromosomes in the human kidney?
there are 46 chromosomes in the human kidney
What are the number of chromosomes in the human gamete?
There are 23 chromosomes in a human gamete
What happens if you have 44 chromosomes in your cells"?
Having 44 chromosomes in your cells can lead to genetic abnormalities or disorders, as the normal human cell typically contains 46 chromosomes. This can result in developmental issues, health problems, or infertility.
