If g=yellow seeds and g=green seeds, a) predict the genotypic and phenotypic ratios of a cross between a heterozygote and a homozygous recessive individual. b) show the genotypic and phenotypic ratios of the f2 of a cross between a gg and gg individual.

a) Genotype ratio= 1/2 Gg: 1/2 gg

Phenotype ratio = 1/2 yellow seeds: 1/2 green seeds

b) Genotype ratio= 1/4 GG : 1/2 Gg: 1/4 gg

Phenotype ratio= 3/4 yellow seeds : 1/4 green seeds

Explanation:

a) Genotype of heterozygote parent plant = Gg

Genotype of homozygous recessive parent plant= gg

A cross between Gg x gg gives progeny in following ratio= 1/2 Gg (yellow seeds) : 1/2 gg (green seeds)

b) Parent plants = GG x gg

F1= Gg

A cross between Gg x Gg would give F2 progeny in following ratio= 1/4 GG (yellow seeds): 1/2 Gg (yellow seeds) : 1/4 (green seeds)

explanation:

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.
