What is the meaning of life?
Vikki [24]
Your life purpose consists of the central motivating aims of your life the reasons you get up in the morning.

Purpose can guide life decisions, influence behavior, shape goals, offer a sense of direction, and create meaning. For some people, purpose is connected to vocation—meaningful, satisfying work. For others, their purpose lies in their responsibilities to their family or friends. Others seek meaning through spirituality or religious beliefs. Some people may find their purpose clearly expressed in all these aspects of life.

Purpose will be unique for everyone; what you identify as your path may be different from others. What’s more, your purpose can actually shift and change throughout life in response to the evolving priorities and fluctuations of your own experiences

Human albinism is an autosomal recessive trait. Suppose that you find a village in the Andes where 1/4 of the population is albi
Aleks04 [339]

Answer:

500

Explanation:

According to the given information, the total number of albino people in the population= 1000/4 = 250.

Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.

The frequency of recessive allele (q) = square root of 0.25 = 0.5

Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5

Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%

Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
