What are some phenotypes that do not vary in a population of organisms? what are some phenotypes that might vary between different populations? do phenotypes have a genetic basis? does inviroment influence phenotype?

1. Phenotypes that decide the decide the development plan of the body do not vary in a population of organisms. Example, the segmentation of the body (number of hands, legs, ears, eyes, etc.).

2. Phenotypes that vary in a population are the eye color, hair color, hair growth, body size, body build, cold tolerance, skin color, etc.

3. Most of the phenotypes have a genetic basis, example, the colorblindness trait that is X linked inherited. But some phenotypes vary epigenetically, e.g., differences in body features of twins.

4. Yes, environment influences the phenotypes. Twins have a genetically identical DNA yet they have minute differences in their skin color, eye color, body build, etc. Such differences arise when the environment differently affects the gene  regulation within the body of the twins.

According to the definition of phenotype, it is physical expression of a genotypes. Hence it is obvious that phenotype has genetic bases.

Yes, environment influences the phenotype.

there is no stairs in bungalow

explanation:

can i have brainliest i need one

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
