What is an exampl of a phenotype?

Question

Like: Purple and White (PPXWW)

Answer 1

A phenotype is the part that is seen (observed). As opposed to a genotype, which may not be expressed.

In the Purple and White example, both are dominant, so if a PP parent and WW parent were to mate, all their kids would be PW's. The PW in this case is both genotype and phenotype, because the phenotype would appear either as a whitish purple or having purple and white spots.

Consider, Pp X Ww. The possible genotypes would be PW, Pw, pW and pw. The possible phenotypes for the genotypes would be as follows:

Genotype - Phenotype.
PW - whitish purple or white and purple spots.
Pw - Purple
pW - White.
pw - whitish purple/ or spots.

Eye color is a good one. If a person's genotype is Brown and Blue, (Brown is dominant and blue is recessive), it would be Brbl. But the eyes would be totally brown (phenotype).

So phenotype is usually an expression of a dominant gene and not a recessive gene, unless the only one present is the recessive gene.

Blood types, eye color, hair color, height, wrinkles in peas, colors of flowers, widow's peak in humans, attached or hanging ear lobes in humans are examples of phenotypes.

Answer 2

The phenotype of an individual organism describes one of its traits or characteristics. This trait is measurable. Only some individuals of that population will show the trait. Examples include "blue eyes", or "aggressive behavior". Some phenotypes are controlled entirely by the individual's genes. Others are controlled by genes but can be influenced by environmental factors. Still other phenotypes are entirely nongenetic, for example, a person's language or physical traits that were altered by surgery.





Many phenotypes are determined by many genes and can also be influenced by environmental factors. Thus, the identity of one or a few alleles of an organism does not always enable prediction of its phenotype.





Scientists use easily observable phenotypes to deduce an organism's genotype. They analyse complex phenotypes to help hypothesize about how individual genes work.

Answer 3

Some examples of phenotypes are:

tall
green seeds
lactose intolerant
sickle cell anemia
vestigial wings

Answer 4

black hair and brown eyes are examples of phenotypes. A phenotype is the visible or physical characteristic that results from a gene.

Answer 5

phenotype is basically the physical characteristic of an an organism. Ex: Tall, short. Gneotype is the the genetic materil Ex: Tt or SS etc. I hope that helped

Answer 6

A phenotype describes any observed quality of an organism, such as its morphology, development, or behaviour, as opposed to its genotype - the inherited instructions it carries, which may or may not be expressed.
