In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). A true-breeding round-leaved, yellow-fruited plant is mated with a jagged-leaves, white-fruited plant. What are the genotypes of the plants involved in this cross

Genotype of true breeding round-leaved, yellow-fruited plant  is RRYY

Genotype of true breeding jagged-leaves, white-fruited plant is rryy

Explanation:

Given -

R represents the allele for round leaves of the tree

r represents the allele for jagged leaves of the tree

R is dominant over r

Also,

Y represents the allele for yellow fruited tree

y epresents the allele for white fruited tree

Y is dominant over y

A cross is carried out between true breeding round-leaved, yellow-fruited plant and  jagged-leaves, white-fruited plant

Genotype of true breeding round-leaved, yellow-fruited plant  is RRYY

Genotype of true breeding jagged-leaves, white-fruited plant is rryy

RRYY * rryy

The gametes of RRYY are RY, RY, RY, RY

The gametes of rryy are ry, ry, ry, ry

Offspring produced by crossing RRYY  and rryy  would have genotyoe RrYy

sunlight and water

explanation:

the correct answer is:

a population changes in response to a change in the environment.
