A phenotype is the whole set of the characteristic of an organism, like physical characteristics (colour of skin, presence of plumes, presence of wings), behavior (like type of nest, nutritional habits and so on).
The phenotype is the result of the so called genotype (the set of inherited genetic information) and of the organism history and experience.
A well stated definition of what stabilizing selection is, so true.
A discrete trait is a trait which doesn't have a range of phenotypes. For example, tongue rolling is a discrete trait as an individual can either roll their tongue or not roll their tongue. There is no phenotype between these two phenotypes.
Aa AA aa If A dominant, two phenotypes.
Yes, when stabilizing selection is acting, individuals with extreme phenotypes are selected against, leading to an increase in the frequencies of intermediate phenotypes within a population. This process helps to maintain the overall consistency of a particular trait or characteristic over successive generations by favoring individuals with traits closer to the population average.
Parental Phenotypes are when the offspring of two parents look like one of the two parents. for example, if a green wrinkled pea is crossed with a heterozygous yellow round pea the offspring are 1/4 yellow round, 1/4 green wrinkled, 1/4 yellow wrinkled, and 1/4 green round. the yellow round and green wrinkled look like the parents so they have parental phenotypes, whereas the yellow wrinkled and the green round have combinations of the parental phenotypes thus they have recombinant phenotypes.
There is no such definition or designation of "race." All humans are a single species, but there are phenotypes which are characteristic differences of expressed genetic traits. Eurasia comprises thousands of languages and peoples ranging from virtually the entire spectrum of phenotypes such as Caucasian, Mongoloid, and so on.
The intermediate phenotypes tend to be selected against, resulting in stabilizing selection that favors the extreme phenotypes. This can lead to a reduction in genetic variation within the population, as individuals with intermediate traits are less likely to survive and reproduce.

No.
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
because no one in this world has the same gene.They may have similar gene,but not the same
