which statements correctly describe mutations in gametes and mutations in somatic cells?
309443
Mutations to gametes can be passed on to an organism's offspring. Mutations in somatic cells are called somatic mutations. Because they do not occur in cells that give rise to gametes, the mutation is not passed along to the next generation by sexual means.

Sex chromosomes. Human chromosomes typically exist in somatic cells as pairs. Normal somatic cells are diploid and contain a total of 23 pairs of chromosomes: 22 of these pairs are autosomes and one is a pair of sex chromosomes. Gametes are haploid, meaning their chromosomes do not exist in pairs.

The two main types of mutations are gene mutations, which can either be point mutations (happening in a single or a few nucleotides) or frameshift mutations (when a nucleotide or nucleotides are inserted or deleted), and chromosomal mutations, which involves changes in the structure or number of the entire chromosome, ...

a, Gametes transmit genes from two parents to offspring. b. You have 46 chromosomes in your somatic cells and 23 chromosomes in your gametes.

2 Answers. They differ in having the number of chromosomal sets. Gametes have the haploid number of chromosomes as the one gamete is able to fuse with another one to form a diploid cell which is the zygote. Somatic cells re diploid cell having two full sets of chromosomes.

In humans, these somatic cells contain two full sets of chromosomes (making them diploid cells). Gametes, on the other hand, are involved directly in the reproductive cycle and are most often haploid cells, meaning they only have one set of chromosomes.

"Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

An allele is an alternative shape of a gene (one member of a pair) this is placed at a particular function on a specific chromosome... Gametes are reproductive cells (sex cells) that unite at some point of sexual reproduction to shape a new mobile called a zygote.

Somatic therapies target genes in specific types of cells (lung cells, skin cells, blood cells, etc), while germline modifications, applied to embryos, sperm or eggs, alter the genes in all the resultant person's cells. ... Germline modifications would be passed on to future generations.

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.

Key Differences Between Mutation and Variations Mutation is the natural and permanent change, causing changes in the DNA or genetic sequence in any living organisms. ... On the other hand variation or genetic variation is seen in groups or population and is observed in genes as well as in alleles.

Two gametes in each pair of cells produced by meiosis are not identical because recombination of alleles (genes) present on two homologous chromosomes occurs during meiosis.

Somatic cells and gametes. -Each body cell contains a set of 46 chromosomes, which come in 23 pairs.

Somatic mutation. If a somatic mutation occurs in a single cell in developing somatic tissue, that cell is the progenitor of a population of identical mutant cells, all of which have descended from the cell that mutated. A population of identical cells derived asexually from one progenitor cell is called a clone.

Like all cells, somatic cells contain DNA arranged in chromosomes. If a somatic cell contains chromosomes arranged in pairs, it is called diploid and the organism is called a diploid organism. (The gametes of diploid organisms contain only single unpaired chromosomes and are called haploid.)

Mutations and sexual reproduction result in increased genetic variation. Mutations can be the result of mutagens or errors during DNA replication. Mutations that are not repaired can become a permanent part of the genetic makeup of the cell.

Hereditary mutations are inherited from a parent and are present throughout a person's life in virtually every cell in the body. These mutations are also called germline mutations because they are present in the parent's egg or sperm cells, which are also called germ cells.
