Answer:

recessive

Explanation:

A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.

A young child runs a fever of 40 °c for 24 hours. explain what effect this may have on his digestion
Lunna [17]

Since the temperature is above 37 degrees, the child’s digestive system will begin to slow down as the enzyme begins to denature because both the internal temperature and the external body heat influence digestive processes. The effect upon the system of the temperature of food and drink is also a matter of significant consideration.

Sladkaya [172]
A person will not pass this mutation onto children because somatic cells cannot go through meiosis if a chromosome in one of the bone cells turn out to be mutated. A somatic cell is any cell that creates up an organism excluding reproductive cell. Which is for example the cells that create up the skin are all somatic cells and definite cells in a living organism support in reproduction, dividing or fusing through the reproductive procedure.
