What can be expected for the recessive trait of monohybrids from the f2 generation?

all dominant traits
all recessive traits
1/3 dominant traits
2/3 recessive traits
none of the above

None of above.

Explanation:

A monohybrid cross uses pure breeding parents to get the F1 hybrid. Self crossing of F1 hybrid gives F2 generation in the phenotypic ratio of 3 dominant :1  recessive. Hence, the expected proportion of recessive progeny in F2 of a monohybrid cross is 1/4 only.

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.
