The directional selection is the type of natural selection, in which an extreme phenotype is promoted due to the changes in the environment. This causes the changes in the allele frequency and the shifting of the phenotype in a particular direction. In this condition, one of the extreme phenotypes are promoted, which result in the shifting of genotypic frequency either of the homozygous characteristics.

In addition, the dietitian will likely offer Patricia more guidelines or tips such as:
****Commencing pregnancy at a healthy weight ( between 25 to 35 pounds), gaining more if underweight or gaining less if obese or overweight.
****Eating moderately but often, focusing on small, frequent meals that are high in lean proteins, fruits and vegetables.
****Drinking enough water ( about ten 8-ounce glasses of water) daily as this helps to aid metabolism and digestion as well as constipation prevention while preventing dehydration.
****Learning how to combine something healthy with less healthy cravings in the event of cravings for less healthy foods
**** Taking exercises such as walking very seriously as it helps to burn a great deal of excessive calories
**** Maintaining a recommended weight region at various stages of the pregnancy which will be in the best interest of mother and child
A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring. The species is the fundamental category of taxonomic classification, ranking below a genus or subgenus. Species names are represented in binomial nomenclature by an uncapitalized Latin adjective or noun following a capitalized genus name, as in Ananas comosus, the pineapple, and Equus caballus, the horse.
2. Logic A class of individuals or objects grouped by virtue of their common attributes and assigned a common name; a division subordinate to a genus.
3. Chemistry A set of atoms, molecules, ions, or other chemical entities that possess the same distinct characteristics with respect to a chemical process or measurement.
