In maize, the genes for curled leaves (cr) and dwarfism (d) are inherited linked. The distance between them is 18 morganids. The plants were crossed with CrCrdd and crcrDD. Determine: 1) genotypes and phenotypes of F1 plants; 2) the expected ratio of phenotypic classes in F2 (offspring from the analyzing crossing of F1 hybrids)
1) Genotype F1 = Crd / crD
phenotype F1: plants of normal growth with normal leaves;
2) in F2: 24.19% dwarf plants with normal leaves, 50.81% plants of normal growth with normal leaves, 24.19% plants of normal growth with twisted leaves, 0.81% dwarf plants with twisted leaves.
