What else can I help you with?
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.
How are scientist able to determine the distance between genes?
Scientists can determine the distance between genes on a chromosome using techniques like genetic mapping. By analyzing the frequency of genetic recombination events between genes, they can estimate the distance between them. Another method is to sequence the DNA and use physical mapping to measure the actual physical distance between genes on the 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
Does mitosis allow genes to move from one chromosome to another?
No, mitosis does not allow genes to move from one chromosome to another. Mitosis is a type of cell division that results in two daughter cells each having the same number and type of chromosomes as the parent cell. Genes are not moved between chromosomes during this process.
What is a chromosome pair that has a extra chromosome attached to it?
A Trisomy 1. Another said this was Down's Syndrome.
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.

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.
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).
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 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.
How are scientist able to determine the distance between genes?
Scientists can determine the distance between genes on a chromosome using techniques like genetic mapping. By analyzing the frequency of genetic recombination events between genes, they can estimate the distance between them. Another method is to sequence the DNA and use physical mapping to measure the actual physical distance between genes on the chromosome.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
What is the difference between nondisjunction and translocation mutations?
Nondisjunction is a mutation where chromosomes fail to separate properly during cell division, leading to an abnormal number of chromosomes in daughter cells. Translocation is a mutation where a segment of one chromosome breaks off and attaches to another chromosome, potentially disrupting the normal genetic sequence.
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."
