Calculate allele frequency: If there are 40 butterflies in a population and 27 of them are yellow, what is the yellow allele frequency?

The frequency of the yellow allele in the 40 butterflies is:

0.675  %

Explanation:

The allelic frequency or genetic frequency is the variant of a gene found in a population.

The sum of the variants of the recessive gene with the normal ones of the population of the dominant gene give 1 (Or 100% of the population)

If a group of 40 butterflies has a dominant gene that makes them yellow, then:

Yellow: Aa. That is the dominant color of butterflies.

Another color: aa. That would the recessive color be in the butterflies.

Aa : 27/40 = 0.675aa : 13/40 = 0.325

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
