Altruism is the selfless behavior shown by an individual that encourages it to help others. As per Hamilton’s rule, an altruistic gene can spread in a population only when the product of fitness benefit ( B ) to the recipient and coefficient of relatedness ( r ) between the altruist and the recipient is greater in comparison to the fitness cost ( C ) to the altruist ( B r > C ) . It is given that the value of r is 0 .5 .

Altruism is the selfless behavior shown by an individual that encourages it to help others. As per Hamilton’s rule, an altruistic gene can spread in a population only when the product of fitness benefit (B) to the recipient and coefficient of relatedness (r) between the altruist and the recipient is greater in comparison to the fitness cost (C) to the altruist (Br>C). It is given that the value of r is 0.5.

An early study found that postal workers who worked in the office had higher rates of coronary heart disease than those who delivered mail on foot. The investigators concluded that physical activity is inversely related to risk of developing coronary heart disease. Sceptics disagreed, pointing out that the postal clerks were older than the postal carriers, and that age is a risk factor for coronary heart disease. This argument highlights the possible role of: -Chance? -Selection bias? -Recall bias? -Confounding?

> Within a certain population, there are exactly 2 alleles at the T locus: T and t. Among the entire population, 30% of the alleles are T. If this population is in Hardy Weinberg equilibrium, what proportions (or percentages, however, you want to express it) will be TT, Tt, and tt? Show work. In a population, there are 75 TT individuals, 25 Tt individuals, and 250 tt individuals. What are the frequencies of T and t? Show work. What are the "expected" numbers of each genotype? Show work. Ís this population in Hardy Weinberg equilibrium? (don't do Chi², just compare your answer in a) b) c) part b io actual and it should be obvious.) ) Assume that, in a population of deer, two alleles exist for eye color. BB deer have blue eyes, Bb deer have purple eyes, and bb deer have red eyes. Out of a population of 1000 deer, 490 have blue eyes. You took notes on the amount of red and purple eyed deer, but your notebook fell in the mud and those numbers are obscured. However, if the population is in…
