Question

If two pea plants having red (dominant) coloured flowers with unknown genotypes are crossed, 75 % of the flowers are red and 25 % are white. The genotypic constitution of the parents having red coloured flowers will (A) be both homozygous (B) one homozygous and other heterozygous (C) both heterozygous (D) both hemizygous

Tardigrade Admin · Accepted Answer

When two pea plants having red (dominant)c coloured flowers with unknown genotype are crossed, the 75 % red and 25 % white flowered plants will be produced by following the law of Mendel. This is possible only if the parents are heterozygotes.
