Answer:

homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. it is referred to by two capital letters (XX) for a dominant trait and two lowercase letters (xx) for recessive trait.

The answer to this question would be: <span>by converting glucose to glycogen. 

Brain cells only able to use energy from glucose, so if the body glucose level is too low the brain cells can't work as it doesn't get any energy/food. When glucose level is decreased, the liver will start to convert glycogen into glucose to keep the glucose level.</span>

ryzh [129]

Answer:

Genes are portions of DNA that contains information to encode proteins

Alleles are different forms of one gene

Chromosomes are closed circular DNA molecules that contain the genetic material of an organism

Explanation:

Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).

Explain how the likelihood of inheriting a mutation from your parents would be based on the type of cell in which the mutation w
Lana71 [14]

Answer:

There is likelihood of inheriting a mutation from your parents would be based on the type of cell in which the mutation was found.

Explanation:

There are two basic types of cell; the germinal cells and the somatic cells. The germinal cells give rise to gamete and these gametes are responsible for the formation of offspring which are produced by the parents. A mutation in any of the gamete that partakes in fertilization will be transferred to the offspring. Mutation that occurs in the gametic cell is called germinal mutation.

The other cell is the somatic cell. The somatic cell are cells in living organism other than the reproductive cell. The somatic cells mutation cannot be transferred to their offspring because most somatic mutations are caused by environmental factors such as radiation and chemicals

A mutant clone might arise if the mutation occurs in a tissue that still has its cell still dividing but if the mutation is in a post-mitotic cell that is, one that is no longer dividing, then the effect on phenotype is likely to be negligible. The result of somatic mutation in a parent can then be transferred to the offspring through the gametic cell
