You have two families of true-breeding diploid Zea mays(maize, corn) plants. Late flowering, with tall stalks Early flowering, with short stalks A cross between these two plants yields F1 hybrids that are late flowering, with tall stalks. Given this information, which alleles are dominant? Explain your reasoning. Using the letters F or f for flowering and T or t for stalk height, indicate the genotypes of the two plants. Plant 1 ______________ Plant 2 ___________________ What is the genotype of the...
