In maize, the genes for curled leaves (cr) and dwarfism (d) are inherited linked. The distance between them is 18 morganids.

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.
