First comes fertilization, when two gametes combine to form a zygote.
1. brown and red in color to help blend into their dry habitat
2. a weasel-like body that helps them maneuver around bushes, trees, and predetors
1. they typically live alone and hunt mainly during the night time. this helps them keep a low profile in large plains
2. they made a wide variety of sounds, some for fun, some for mating, some to luring prey
Mutation can cause instant adaptation while natural selection is the process by which adaptation occurs over a series of generations.
The scenario will be Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son
<h3>What is color blindness?</h3>
The condition is frequently inherited. Certain eye diseases and medications are also possible causes. Men are more affected than women.
Color blindness is characterized by the inability to distinguish between red and green shades.
A colorblind man's genotype is XcY, and a heterozygous carrier female's genotype is XcX. A cross between XcY and XcX would result in progeny with the following ratio=
Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son.
Thus, the couple is likely to have a son who is half normal and half affected. Similarly, the couple is likely to have 50% normal daughters and 50% colorblind daughters.

The tissue in the wall of the uterus that is required for labor contractions are SMOOTH MUSCLES. Smooth muscles, also known as involuntary muscles are found in walls of hollow organs such as the stomach, gullet, bronchi, etc. Smooth muscles principally function as stimulator for movement. Examples of smooth muscles in the human body include:
1.Uterus smooth muscles: enhancing pushing during birth labour
2. Bladder smooth muscle: helps push out urine.
3. Smooth muscles also help the flow of blood in the blood vessels and the flow of food through the digestive system.<span />
