After self pollination of red flowered plants out of 40 plants of progeny were white flowered. this indicates that the plants are__________________?

Question

Accepted Answer

Heterozygous. Self-pollination of red-flowered plants producing white-flowered progeny indicates that the parent plants carried a recessive allele for white flowers. This segregation pattern (3:1 ratio implied by 'out of 40') is characteristic of heterozygous parents (Rr x Rr) where the dominant trait (red) masks the recessive one (white) in the parents but expresses in some offspring.
