Look at the population pyramid. What conclusion can you draw from it?
balu736 [363]

c. Birth rates are high      

Explanation:

A wide base in the population pyramid shows that there is a large population of young people with high fertility rate or birth rate and high death rate.

From the graph, it can also be concluded that narrow tip at the top shows that lesser older people are in the population.

This pyramid shown in the diagram is a triangular age pyramid. In this type of pyramid the pre-reproductive individuals are high   reproductive individual are moderate and non-reproducing individual is less. In such pyramid we find population grows.

Suppose in a family of ten 6 are pre-reproductive, 2 moderate reproductive and 2 post-reproductive. We will see the in the course of moderate and post-reproductive will die and those six of pre-reproducing age will increase the population.

How is the blending theory of inheritance useful in genetics?
makkiz [27]

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

<h3>What is blending inheritance?</h3>

Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.

As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance.

Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

Thus, this can be the importance of blending inheritance.
