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.

In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l

melisa1 [442]

The answers would be:

Genotype Phenotype

Tt Tall stemmed

tt Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1

You can read on to see how this was done:

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

t t

T | Tt | Tt

t | tt | tt

Let's list down the genotypes and phenotypic results.

Genotype no. Phenotype

Tt 2 Tall stemmed

tt 2 Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2 or 1:1
