A recessive trait is observed when an organism has 2 recessive genetic factor

Option C

Explanation:

According to the Mendel’s law of inheritance there are two traits. Dominant and recessive. Usually the recessive are submissive genes which cannot express their characteristics. The dominant trait are the ones which expresses the characteristics.

Two copies of recessive allele are required for the recessive trait to be produced. The recessive trait will be expressed by each parent contributing one allele towards the offspring.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
