Here are the four postulates of natural selection, according to Charles Darwin:
1. variability - refers to different mutations that create different species
2. heritability - refers to the genes that are passed from one organism onto its descendants
3. overproduction of offspring - refers to the fact that more "children" is born than dies
4. natural selection - refers to those organisms that survive because they adapt to their surroundings better than those who will die

Answer:
Explanation:
<em>A diagram of a Punnett Square showing the chromosomes involved in the inheritance of sex-linked traits.
</em>
<em>The female had the genotype XHXh, and produced the two gametes seen at the left side of the diagram.
</em>
<em>The male had the genotype XHY0, and produced the two gametes seen at the right side of the diagram.
</em>
<em>The genotypes seen in the center of the square represent the possible genotypes of the F1 generation.
</em>
<em>Two female offspring are produced for every two male offspring.
</em>
<em>One male and one female offspring inherit normal genes.
</em>
<em>One female is heterozygous for the hemophilia trait and is considered a carrier.
</em>
<em>One male receives a damaged X-chromosome and inherits the condition known as hemophilia.</em>
