Question

let ( p = ) purple flowers and ( p = ) white, and ( t = ) tall plants and ( t = ) dwarf. what would be the appearance of a plant with the genotype ( pptt )?
multiple choice
pale purple flowers, intermediate height
white flowers, dwarf
purple flowers, tall

Explanation:

Step1: Determine flower color

In genetics, when an organism has a heterozygous genotype (like \(Pp\) for flower color), the dominant trait is expressed. Here, \(P\) (purple) is dominant over \(p\) (white). So for the \(Pp\) part of the genotype \(PpTt\), the flower color is purple.

Step2: Determine plant height

For the height trait, \(T\) (tall) is dominant over \(t\) (dwarf). Since the genotype is \(Tt\) (heterozygous), the dominant trait (tall) is expressed.

Answer:

purple flowers, tall
