A scientist is studying a plant species with two possible flower colors: red (R) and white (r). The gene for flower color has two alleles: R (dominant) and r (recessive).
If a plant has the genotype Rr, what is its phenotype?

Two children of the same parents have some similar traits, but overall look very different. How is this possible?
They each get multiple traits from their parents, both mother and father. This results in many different possibilities of trait combinations to be present in the children
