Three-fourths (3/4) of the plants produced by a cross between two unknown pea plants have red flowers and ¼ have white flowers. What are the genotypes of the parent plants? Explain using a punnett square and in written form.

i do not know and i have a 100 in this class

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

sorry, but you do not have posted the diagram.
