This relates to Mendelian genetics and the concept of dominant and recessive alleles in a diploid gene. Under this understanding, you could say for example that the allele for light coloured moths is L whereas that for dark coloured moths is l. If l is recessive to L, then moths of the genotype LL and Ll would remain lightly coloured, whereas moths with the genotype ll would be dark coloured. Even if the environment selected out dark coloured moths, these would only be the moths with the genotype ll, and those remaining, LL and Ll, could still cross to produce LL, Ll and ll genotypes. This is how dark coloured moths can remain in the population even though they are actively selected against.
Answer:
Publication bias is the phenomenon where positive trials are more likely to get published than negative ones, and it can happen for a huge number of reasons, sinister and otherwise. Major academic journals aren't falling over themselves to publish studies about new drugs that don't work.
Restriction enzymes are DNA-cutting enzymes found in bacteria (and harvested from them for use). Because they cut within the molecule, they are often called restriction endonucleases.
Answer:
insulin and Glucagon If blood glucose levels rise (for example, during the fed or absorptive state, when a meal is digested and the nutrient molecules are being absorbed and used), the beta cells of the pancreas respond by secreting insulin.
Explanation:
The three parts of amino acid are, the carboxyl group, amino group, and the R group.
