Finding an occasional vermillion-eyed female can be explained by the occurrence of an extra chromosome from the for the trait?
It is likely that the vermillion eyes in the female are due to a random genetic mutation or chromosomal abnormality, rather than a specific gene. The presence of an extra chromosome could disrupt normal eye pigmentation, resulting in the unique color. This occurrence is rare and may not follow typical inheritance patterns.
How do the cells of people with down syndrom differ from those of others?
People with Down syndrome have an extra copy of chromosome 21 in their cells, leading to 47 chromosomes instead of the usual 46. This genetic condition can result in various physical and cognitive differences, such as distinctive facial features and intellectual disabilities, compared to individuals without Down syndrome.
How can nondisjuncton result in an individual having an extra chromosome what is this called?
Yes, nondisjunction results in a germinal cell (ovum or spermatozoa) with either too many or too few chromosomes. If one of these cells joins with another to form a zygote, there may be one or more too many or too few chromosomes in the cells.
What types of Down syndrome are there?
There are three different types of Down syndrome: Standard Trisomy 21, Translocation, and Mosaicism. Standard Trisomy 21 is when the extra chromosome 21 comes from either the egg or sperm cell. Between 90% and 95% of all Down syndrome is Standard Trisomy 21.
Trisomy is a mutation that results in a cell having an extra?
A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. A person can have full trisomy (three copies in every cell) or mosaic trisomy (three copies in some cells but not all).
How does the cell adjust to the extra X chromosome in female cells?
In females, the extra X chromosome becomes inactive and becomes the Barr body.
Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells of humans this extra chromosome occurs in the gamete as a result of?
an error in meiotic cell division
How do cells of people with Down syndrome differ from those of others?
They have an extra chromosome 21.

What is the medical condition mosaicism?
A type of trisomy, where only some of the cells in the body have the extra chromosome.
What condition results when cells receive 3 copies of chromosome twenty one?
Down syndrome occurs when an individual receives an extra 21st chromosome.
Do all cases of down syndrome have a complete extra chromosome?
No, not all cases of Down syndrome involve a complete extra chromosome. The most common form, known as trisomy 21, consists of an entire extra chromosome 21, resulting in three copies instead of the usual two. However, some cases are due to a Robertsonian translocation, where a part of chromosome 21 is attached to another chromosome, or mosaic Down syndrome, where some cells have the extra chromosome while others do not.
What condition occurs when a person's cells have an extra copy of chromosome 21?
down syndrome !! hope this helps

What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
What is the term for an individual who has an extra copy of one chromosome or is missing a chromosome - Is it something-'ploid'?
Aneuploid - the individual has an extra copy of one chromosome or is missing a chromosome.
How does trisomy occur?
Trisomy occurs when an individual has three copies of a particular chromosome instead of the usual two. This can happen during the formation of sperm or egg cells, leading to an extra copy of the chromosome in the resulting embryo. Trisomy can result in conditions like Down syndrome, where there is an extra copy of chromosome 21.
