Explanation:
Frequency of blue allele is
Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR
Frequency of other allele
Chi Square test

Answer: Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. ... As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.
Explanation:
The right answer is A mutation.
Alteration of the genetic material (DNA or RNA) of a cell or virus that causes a change in certain traits due to the inheritance of this genetic material from generation to generation.
Abnormal modification of the DNA of a gene, either spontaneously during cell division, or under the influence of external agents called mutagens. This gene is modified to be transmitted to the daughter cells. Some mutations have no effect on the cell. Others are the first step in a long process of cancerization.
Rare are the mutations that are beneficial.
The neurotransmitter is Dopamine.
The following combinations of neurotransmitters seem to be at play in
those who suffer from ADHD is Serotonin, dopamine, and norepinephrine. Neurotransmitters,
also known as chemical messengers, are endogenous chemicals that enable
neurotransmission. They transmit signals across a chemical synapse, such as a
neuromuscular junction.
