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.

A somatic cell having two of each type of chromosome has chromosome number?
Diploid
A gene located on the X or Y chromosome is a?
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
What is having one of each type of chromosome characteristic of the species?

What is having only one of each chromosome in the cell called?
Having a single copy of each chromosome is called the haploid condition eg in egg and sperm cells.Having pairs of chromosomes is called the diploidcondition eg in all other body cells (except red blood cells which do not have chromosomes).
What does an individual with an extra copy of chromosome 21 demonstrait traits of having?
down syndrome
What is a sat chromosome?
A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
The amelogenin gene can be used to determine?
The amelogenin gene can be used to determine the sex of an individual. It has two forms, one found on the X chromosome and one on the Y chromosome. By comparing the length of these forms through a technique like PCR, researchers can identify whether an individual is male (having both X and Y forms) or female (having two copies of the X form).
What is sat chromosome?
they are chromosomes having secondary contriction.. aka satellite chromosome
A somatic cell having two of each type of chromosome has chromosome number?
Diploid
Down syndrome is usually caused by an extra copy of what chromosome?
Down syndrome occurs because of the extra chromosome on chromosome 21. If you go onto google images and type in karyotype of Down syndrome, you will find a picture of the extra chromosome. Instead of having two chromosomes on chromosome 21, there is an extra. Type your answer here...
What is X chromosome?
The X chromosome is one of the two sex chromosomes in humans, with the other being the Y chromosome. It carries genes that determine an individual's biological sex, with females having two X chromosomes (XX) and males having one X and one Y chromosome (XY). In addition to sex determination, the X chromosome also carries various genes that play roles in development and other biological functions.
What is Meta-female?
It is the female having one additional X chromosome making her genotype 44 + XXX called meta female It is also called Super female
Is Down syndrome a genetic disorder or a chromosome disorder?
Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
A gene located on the X or Y chromosome is a?
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
Why Males having a greater chance of hemophilia?
Hemophilia occurs in the X chromosome, and males are the genders that have the X chromosome.
