How do you see mutation in a karyotype?
You might see an extra chromosome or a missing chromosome. You might see a piece of a chromosome missing, or a piece added onto another chromosome.
What technique do geneticists use to count and study an individual's chromosome?
Geneticists use a technique called Karyotyping. Scientists take a picture of chromosomes and then arrange them in pairs to end up with 22 chromosomes and another pair that determines sex; chromosome (X,X ) for female or (X,Y) for males. Then you can determine mutation when some chromosomes are missing, ex: missing chromosome 13 will result in Patau Syndrome, or missing chromosome 18 results in Edward's Syndrome
What terms refers to both the movement of a ribosome along a piece of mRNA and the movement of a piece of one chromosome to another chromosome?
Translation
What is a chromosome pair that has a extra chromosome attached to it?
A Trisomy 1. Another said this was Down's Syndrome.
How do chromosomes determine sex?
In Human Beings two chromosomes normally determine a persons sex. If a person has two X chromosomes, (XX), that person will be a female. If a person has an X and a Y chromosome, that person will be a male. Most people get 23 chromosomes from their mother and 23 from their father. Thus, most people have 46 chromosomes. They get either an X or a Y chromosome from their father. Sometimes things get complicated. That is for another answer.
What are 2 possible end results of meiosis?
There could be 4 daughter cells with half the chromosomes as the original. Another outcome is crossing over in which one allele from one chromosome changes positions with an allele from another chromosome.
What does the 23 pair chromosome determine?
The twenty-third pair of chromosome determines gender. Males are distinguished of having an X and a Y. Females are distinguished to have a X with another X.
What does chrimatid mean?
A chromatid means one copy, or a daughter cell, of a duplicated chromosome, which is joined to another copy by a single centromere. Each contain the same DNA and chromosome protein as the original cell.
What is difference between chromosome and chromatids?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere. They are known as sister chromatids. Once the paired sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.

Does the male or female determine the gender in humans?
It is the x or y chromosome in the sperm of males that determine the sex of the baby. The woman carries two x chromosomes and the sperm either carries another x (a girl) or a y (a boy).
What can one half of a duplicated chromosome be referred as?
A chromatid is one-half of two identical copies of a replicated chromosome. During cell division, the identical copies are joined together at the region of the chromosome called the centromere.Joined chromatids are known as sister chromatids. Once the joined sister chromatids separate from one another in anaphase of mitosis, each is known as a daughter chromosome.Chromatids are formed from chromatin fibers.Bailey, Regina. "Chromatid."

How do you see mutation in a karyotype?

What is another word for colored bodies?
Chromosome
What sex chromosome is present in all humans?
There are two sex chromosomes: the X chromosome and the Y chromosome. During fertilization, the mother always gives an X chromosome and the father gives either another X chromosome or a Y chromosome. Therefore, all humans have at least one X chromosome.
A characteristic of an organism that is determined by many genes?
The terms used to describe a number of genes on separate loci on the same chromosome (or another chromosome) which together determine a single phenotypic trait are polygene, multiple factor, multiple gene inheritance or quantitative gene.
What technique do geneticists use to count and study an individual's chromosome?
Geneticists use a technique called Karyotyping. Scientists take a picture of chromosomes and then arrange them in pairs to end up with 22 chromosomes and another pair that determines sex; chromosome (X,X ) for female or (X,Y) for males.

Do you die if you have another 13 chromosome?
Actually Yes you would
