Question at position 25

Two plants are crossed, and the traits of height and color are assessed in the offspring. The following cross was conducted: TTPP x ttpp.

T = dominant allele for height, tall plant

t = recessive allele for height, short plant

P = dominant allele for color, purple

p = recessive allele for color, white



Which of the following choices correctly describes the offspring?




All are short and white

All are tall and purple

Three quarters of the plants are short and white

Three-quarters of the plants are tall and purple.

Answer 1

All are tall and purple

Explanation: TTPP x ttpp produces only TtPp offspring (heterozygous for both traits), and the dominant alleles (T and P) give the tall and purple phenotype.
