Waec Model Questions Vol1 2019 Biology Question 16
Practice objective / multiple choice question 16 from the 2019 Waec Model Questions Vol1 Biology examination.
In corn, kernel colour is controlled by two genes: C (colour) is dominant over c (colourless), and W (white) is dominant over w (yellow). The presence of at least one C allele gives colour, but if the genotype is cc the kernels are colourless regardless of the W gene. A plant heterozygous for both genes (CcWw) is crossed with a plant homozygous recessive for colour (ccww). What proportion of the offspring will have white coloured kernels?
