In tomato plants, purple leaf color is controlled by a dominant allele A, and green leaf by a recessive allele a. At another locus, hairy leaf H is dominant to hairless leaf h. The genes for leaf color and leaf texture are separated by 16 m. u. on chromosome 5. On chromosome 4, a gene controlling leaf shape has two alleles: a dominant allele C that produces cut-leaf shape and a recessive allele c that produces potato-shaped leaf.
a. The cross of a purple, hairy, cut plant heterozygous at each gene to a green, hairless, potato plant produces the following progeny:
Phenotype Frequency %
Purple, hairy, cut 21
Purple, hairy, potato 21
Green, hairless, cut 21
Green, hairless, potato 21
Purple, hairless, cut 4
Purple, hairless, potato 4
Green, hairy, cut 4
Green, hairy, potato 4
