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).

In place of thymine, what does RNA use as a base Please help

11111nata11111 [884]

The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.

The thyroid gland is sensitive to the amount of iodine in the blood. If there is not enough iodine, the thyroid gland can:

ankoles [38]

Answer:

The thyroid gland increase in size.

Explanation:

Iodine plays an important role in the generation of thyroid hormones and is mainly found in the soil in coastal areas and in seawater. In the developing nations, the individuals who live at high elevations or inland are generally deficient in iodine and can develop a condition known as goiters.

In the condition, the thyroid gland increases in size in an attempt to get more iodine. However, in the countries where iodine is added routinely to foods and table salt, the lack of dietary iodine is not the typical reason of goiters.

What makes red blood cells unique compared to other cells in the body

alex41 [277]

"The red blood cell survives on average only 120 days. Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled." - hematology.org
