1. What is phenotypic plasticity?
2. How can the same genotype result in multiple phenotypes?
3. What effect do environmental conditions have on gene expression?

Answer 1

1. Phenotypic plasticity is the ability of one genotype to produce more than one phenotype.
2. The same genotype can result in multiple phenotypes due to changes in environmental conditions.
3. Environmental factors can influence how genes are expressed. This leads to phenotypic plasticity.

Question 2

Can one genotype exhibit many phenotype?

Answer 2

Yes, and it’s called phenotypic plasticity

And it can be due to environmental factors

Question 3

What’re some examples of phenotypic plasticity?

Answer 3

1. Hydrangea plants, where the color of the plant is determined by the soil pH
2. Number of stomates in the plant is determined by atmospheric conditions
