Question

Which of the following is phenocopy? Please give the answer in details. Promise to mark you as brainliest

Answer 1

Answer:

Option 2 is the phenocopy.

If a genotype mimics the expression of another one it's called Phenocopy. Phenocopy is not heritable character.

Here in second option Tt which is the genotype for tall plant but its phenotype is of dwarf plant so it is mimicking the expression of other so it is a phenocopy.

Answer 2

Option 2 is an example of PHENOCOPY.

Definition of PHENOCOPY :

PHENOCOPY is a phenomenon in which an organisms phenotype is is environmentally determined and similar to another organism whose phenotype is determined genetically.

Let's see OPTION 2 :

$\sf{tt \: \: \longrightarrow \: Dwarf \: plant} \\ </p><p> \sf{Tt \: \: \longrightarrow Dwarf \: plant}$

Here , tt genotype would result in dwarfness in plants.

Tt genotype usually results in tall plants , but in this case it is forming dwarf plant. The phenotype of the second plant is determined environmentally during its development

Hence this is an example of PHENOCOPY.
