According to Charles Darwin's theory of Evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

One word answer:Adaptation:
Every species exhibits variations based on various genes being activated at various times. An example with humans can be eye color or hair color. What species means is that all members of a species can procreate with healthy, capable of procreating progeny, but anything else is just a variation.

Explanation:
Complete question:
Punnet squares for genes found in sex chromosomes are unique in that the pattern of inheritance of these traits is gender-specific. For example, examine the following Punnet square for color blindness, a trait found in the X chromosome (Y chromosome carry only a few genes but they do not possess enough coded information to initiate the development of the male).
Xcb represents the X chromosome carrying the color blindness trait. The allele for color blindness is recessive to the normal form of the gene (X).
Punnet square:
Mother
Xcb X
Father X X Xcb X X
Y Xcb Y X Y
Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype?
Answer:
<em>YES. Male and female offspring </em><u><em>will have the same likelihood</em></u><em> of carrying the colorblindness trait in their genotype. </em>
