Do all somatic cells have the same genes on the same chromosomes?
OneClass: In your body, all somatic cells (not sex cells) have the same DNA.
How many alleles do somatic cells have?
These slightly different gene sequences at the same genetic locus are called alleles. While there can be only two alleles for a given locus in the genome of a single individual, there can be many dozens of alleles in the whole population.
What do all somatic cells have in common?
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring.
Are all somatic cells identical?
In humans, such cells are diploid and reproduce using the process of mitosis to create identical diploid copies of themselves when they split. … Other types of species may have haploid somatic cells, and in these individuals, all of the body cells have only one set of chromosomes.
Do all somatic cells have the same DNA code?
Yes, the DNA code is the same in every somatic cell in the human body.
Why do somatic cells have 46 chromosomes?
Each pair of chromosomes comprises one chromosome inherited from the father and one inherited from the mother. For example, in humans, somatic cells contain 46 chromosomes organized into 23 pairs. … Due to the fusion of the two gametes, a human zygote contains 46 chromosomes (i.e. 23 pairs).
