A red-eyed individual is crossed with a white-eyed individual to produce F1 progeny with red eyes. When F1 individuals are intercrossed, F2 progeny is formed with both red as well as white-eyed individuals.
(a) How is the dominant trait identified?
(b) What are recessive traits?
(c) If 12 individuals are produced in F2 generation, then how many white-eyed individuals would be obtained? Calculate the ratio of red-eyed individuals white-eyed individuals.
(a) the F1 progeny is only red eyed individual. so, the red eye is the dominant trait.
(b) the traits that cannot express themselves in the presence of a dominant trait.
(c) 3 white eyed individuals
red eyed : white eyed
