1 answer:

<span>This suggests that the trait observed is a single allele dominate trait and that both parents were heterogeneous in that they had a copy of both the dominate and the recessive allele. For the offspring, the 1/4 of the population that doesn't show the trait, all of them have the recessive allele. Of the 3/4ths that show the trait, 2/3rds of them will also be heterogeneous like their parents, and 1/3rd will be homogeneous in the dominant allele.</span>

What are some of the concerns associated with our increasing population and consumption of resources?

Ugo [173]

Explanation:

As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.

Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.
