How does a normal karyotype looks like?
Two straight lines
The two chromosomes in each matching pair in a karyotype are?
homologous chromosomes- Erick Rosales
How many copies do you have of each chromosome?
There will be two copies of each chromosome in all somatic cells called homologous chromosome..In case of reproductive cells there will be only one set during gamete formation...
How do germ-cells make a single set of genes from the normal two copies that all other cells in the body have?
If progeny plants inherited a single whole gene set from each parent, then the aw of independent assortment would not work. this is because two different characteristics would be linked to each other and cannot be independently inherited. This is explained by the fact that each gene set is present not as a single long thread of DNA, but as separate independent pieces, each called a chromosome. Thus, each cell will have two copies of chromosome, one each from male and female parents. Each germ cell will take one chromosome from each pair and these may be either of maternal or paternal origin. When two germ cells combine, they will restore the normal number of chromosomes in the progeny, ensuring the stability of the DNA of the species.
What are pair of similar chromosomes called?
HomologousWe receive one complete set of chromosomes from each parent. This means that for each chromosome, say chromosome 7, there are two copies in every cell of our bodies: the maternal and paternal copies of chromosome 7.The two copies of one chromosome are called a pair of homologous chromosomes.
Does your karyotype represent a male of a female?
The question is not really clear. A karyotype is the overall complement of chromosomes isolated from a cell or organism (eukaryotic). When the karyotype of a normal healthy female is prepared for viewing by a cytogeneticist, there are 22 pairs of autosomal chromosomes present (ie two of chromosome 1, two of chromosome 2 etc...). There is one additional pair of sex chromosomes (two copies of X). A normal healthy human male also has 22 pairs of autosomes but the pair of sex chromosomes is not matched but instead there is one X chromosome and one Y chromosome (which is smaller than the X). So, if you look at a karyotype that has been laid out - if the two sex chromosomes are different sizes (X and Y) then the karyotype is from a male, if however they are the same size (X and X) then the karyotype is from a female.
What is a karyotype and what type of mutation does it show?
A karyotype is a picture of the chromosomes in a cell. For example, a human cell has 46 chromosomes. In the karyotype, 23 pairs of chromosomes will be shown (23 x 2 = 46). A karyotype can show different types of mutations, depending on which chromosome it affects. For example, Down Syndrome is a trisomy in chromosome 21, so there will be THREE instead of two chromosome 21s. You can research more mutations shown by chromosomes in a karyotype.

How many autosomes are present in a normal human karyotype?
There are 46 chromosomes in a human Karyotype.
How the karyotypes of klinefelter syndrome differ from the normal karyotypes?
The karyotype of a person with Down Syndrome differs from a normal karyotype because it contains a three chromosomes in the 21st slot, where there should only be a pair of two. That is why this is called Trisomy 21.
What is the name of the chart used to determine a person's sex?
It is called a karyotype. If it shows two X chromosomes, the person is a female; if it shows one X and one Y chromosome, the person is a male.
What does the karyotype of a person with down syndrome show?
A genetic disorder caused by the presence of all or part of a third copy of chromosome 21.
The two chromosomes in each matching pair in a karyotype are?
homologous chromosomes- Erick Rosales
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...
A somatic cell having two of each type of chromosome has chromosome number?
Diploid
How many chromatids does each chromosome have before S-phase?
There are two chromatids for each chromosome before the S-phase. The S-phase is wherein DNA of each chromosome is replicated.
A cell condition in which each chromosome is doubled?
the two halves of a doubled chromosome structure are called?
