The frequency of a lethal allele in a population is greatest when it is: Group of answer choices dominant manifested in infancy

bonufazy [111]

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.

How does the concept of a circle relate to cyclins?

baherus [9]

The progression of a cell by the cycle of cell is regulated by the protein family Cyclic

Explanation:

In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell.
CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell.
The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.
