How are genetic mutations passed from parent to offspring?

Genetic mutations are passed from parent to offspring by mutated gametes (sex cells) which are fuse to create offspring.

Further Explanation:

Sexual reproduction is the major method of reproduction in a variety of organisms. All the plants and animals majorly undergo sexual reproduction. The main process in sexual reproduction is:

Meiosis

Fertilization

Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation.

Germline or genetic mutations can be defined as the lasting change in the sequence of germ cell (sperm and ovum) DNA. These mutations can inherit from one generation to another. If a mutated gametes such as oocytes or sperm fuses with other. After fertilization, meiosis occurs and crossing over takes place which transfer the genetic information from parents to offspring. If the genetic information contains mutated gene that is also pass from parents to offspring.

Ans. (B). Mutated gametes (sex cells) fuse to create offspring.

Genetic mutations or germline mutations can be defined as permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other, when a mutated sperm or mutated oocyte (gametes) get fertilized with other oocyte or sperm.

A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, as single-celled zygote divides and produce all of the cells in that organism.

Thus, the correct answer is option (B).

Answer:

According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.

Explanation:

G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.

G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.
