Suppose that the proportion of the white crest alleles (r) is given by w and that of the Red crest allele (R) is given by p. We have that p+w=1. The probability that an individual has 2 r alleles is given by w*w since for each allele position the probability is w. Only these individuals have a White phenotype. Hence, we get that w^2=

; the right hand side is the proportion of white birds in the total population. Doing the calculations, this yields that w=0.37. From this, we calculate that p=0.63. The possible ways we have heterozygous individuals are the combinations Rr and rR. The probability for each of those is p*w. Thus, the total probability is 2pw. This is equal to 0.466=0.47. This is the fraction of the future population that is going to be heterozygous assuming the conditions of the Handy-Weinberg equilibrium like random reproductive matching etc.

A psychological disorder or a mental disorder is compose of behavioral and psychological symptoms impacting on areas of one's life causing further problems. When a psychiatrist like Dylan works on the causes of the disorder such as chemical imbalances, he is now working on the Biological perspective of the treatment.
230 is your anwser! sorry bad english
Increase in urbanization will lead to increase in the number of people who are living in an urban area and it will also lead to increase in development in that area. The increase in development can come in form of construction of industries, which release large amount of waste products that pollute the air. This will lead to air pollution and reduce air quality. Development can also be in form of availability of electricity, that makes it possible for people to operate different electrical gadgets such as radio and television, which can result in noise pollution. Increase in the number of people who operate motor vehicles will also lead to increase in air pollution, which is caused by fossils fuel.
