Human birth weights range very narrowly between 5.5 and 8.5 pounds. Babies much smaller than 5.5 lbs. suffer a higher mortality
due to low birth weight, while babies much larger than 8.5 lbs. can cause complications during birth and also have a higher mortality rate. This is an example of:a. Stabilizing selection b, Sexual selection c. Genetic drift d. Reproductive isolation e. Disruptive selection
Babies lower than 5.5lbs would suffer from various disorder because of low birth weight as their body would not be able to compete as well they would have weak immune system and malnourishment. Whereas high birth weight carry the equally above risk as their body wont be able to cope up and organs become insensitive to various hormones. for the survival the birth weight should be within a median range so that it would be favorable for themselves and surroundings.
Stabilizing selection occurs when a population stabilizes on a particular trait value and genetic diversity decreases. As in this example, an average baby weight has to favour against extreme variation for it's better survival.
therefore, this is an example of stabilizing selection.
DNA (Deoxyribonucleic acid) is the genetic material present inside the nucleus of all eukaryotic cells.
Samples as small as few skin cells also contain DNA and the presence of DNA in skin cells is often used to identify the DNA of a person in a crime scene.
Further, with the use of PCR technology, the small amount of DNA obtained from skin cells can be amplified into many copies.
<span>Adaptation is a change or the process of change by which an organism or species becomes better suited to its environment.
