The expression of certain genes at different levels may cause color variation in the butterfly wings.
<h3>What is gene expression?</h3>
Gene expression is the cellular process associated with the transcription of certain genes in particular cell types.
In this case, the trait color in butterfly wings is associated with the differential expression of certain genes during development.
The variation in color may be due to the expression of different alleles in butterflies or the same allele at different levels.

Answer:
Genetic drift
Explanation:
Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.
Hello!
The parts of the central nervous system (CNS) include only the following:
Most of the other parts we associate with the nervous system are part of the PNS, or the peripheral nervous system.
