Two traits (stem length and seed color) are simultaneously examined in a cross of two pure-breeding pea plant varieties. A tall green plant is crossed with a dwarf yellow plant, and the resulting F1 plants are self-crossed. A total of 640 F2 progeny are phenotypically characterized as follows:
tall yellow = 360
tall green = 120
dwarf yellow = 120
dwarf green = 40
What is the dominance relationship for plant height? for seed color?
What is this asking? Does dominance relationship refer to which allele/phenotype is dominant over the other (in which case, the tall phenotype is dominant over the dwarf phenotype, and yellow seed color is dominant over green seed color)?
