A given gene is present on exactly two chromosomes in a somatic cell.
my Doctor told me that there is DNA with one strand and there is with three and if i prove that he will award me so please help me
At the end of telophase, there are two sets of replicated chromosomes present in each cell. This is because during telophase, the duplicated chromosomes have separated and two identical sets of chromosomes are formed in preparation for cytokinesis.
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
If both members of a pair of chromosomes are present in the cell, the condition of the chromosomes is said to be diploid. Diploid cells have two sets of chromosomes, one set derived from each parent.
The probability of a specific gene being passed on from a parent to their offspring is 50% for each parent. This is because each parent contributes one copy of each gene to their offspring. Therefore, the likelihood of inheriting a specific gene from one of many genes on a chromosome is dependent on the genetic makeup of the parents.
Typically, there are two alleles present in a gene, one inherited from each parent.
The kind of alleles for a gene that are carried on homologous chromosomes are many. These are for similar genes which may be slightly different like the eyes, hairline, dentures and so much more.

It depends on which chromosomes were present as to what the abnormality would be, if any. If they were missing one or had one extra there would be developmental abnormalities.
At the end of telophase, there are two sets of replicated chromosomes present in each cell. This is because during telophase, the duplicated chromosomes have separated and two identical sets of chromosomes are formed in preparation for cytokinesis.
A somatic cell typically contains 46 individual chromosomes. These chromosomes exist in pairs, with one set inherited from each parent.
There is no one gene for schizophrenia. However, there are many different genes that may contribute to schizophrenia. A gene on chromosome 1 in the 22 family is implicated in schizophrenia, as well as genes on chromosomes 11 and 6.
Homologous chromosomes are present in diploid cells, which contain two sets of chromosomes (one inherited from each parent). In contrast, haploid cells contain only one set of chromosomes.
Chromosomes. Strictly speaking they are not halves but just grouped into pairs. A pair represents a gene.
One of the different alleles would be at the same gene locus on each of the paired chromosomes.
A sex linked trait.
X-linked refers to a gene carried on the X chromosome, one of the two sex chromosomes.
