One purpose of meiosis is to keep the number of these constant in generation after generation of zygotes?
chromosomes
What is the adjective referring to the number of chromosomes in a gamete?
Diploids and Haploids. Haploids have one set of chromosomes (Gametes). Diploids have two sets of chromosomes (Zygotes).
Why a person with Down's syndrome has an abnormal number of chromosomes?
Yes.
Normal mice gametes 20 chromosomes. how many chromosomes do normal mice zygotes contain?
The answer is 40
Why might Cells from an advanced malignant tumor most often have very abnormal chromosomes and often an abnormal total number of chromosomes?
Chromosomally abnormal cells can still go through cell cycle checkpoints.
What occurs during nondisjunction?
If nondisjunction occurs, abnormal numbers of chromosomes may find their way into gametes, and a disorder of chromosome numbers may result.
What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes contain 12 chromosomes each?
It will be 24 in the zygote since zygote is diploid cell and gametes are haploid.
How mice gametes contain 20 chromosomes. How many chromosome do normal mice zygotes contain?
Since the gametes contain one half the number, the zygote will have to have the full number of 40.
What is nondisjuction?
Cell division in which the sister chromatids do not separate correctly, resulting in gametes with an abnormal number of chromosomes.
Does a mongoloid baby be cure?
I think you are referring to Down's syndrome. It is due to abnormal number of chromosomes in the cells There is no cure.
What characteristics does an abnormal genetic test have?
An abnormal chromosome analysis report will include the total number of chromosomes and will identify the abnormality found. Tests for gene mutations will report the mutations found.
How can karyotypes detect non disjunction?
Karyotypes can detect non disjunction by showing abnormal chromosome numbers. Non disjunction occurs when chromosomes fail to separate properly during cell division, leading to an imbalance of chromosomes in the resulting cells. Karyotypes can be analyzed to identify any extra or missing chromosomes, indicating the occurrence of non disjunction.
