by grouping images of a fetus' homologous pairs together and arranging them by shape and size, scientists can easily see whether
the baby has

Explanation:

Genetic conditions such as trisomy (three chromosomes) or monosomy (only one chromosome). They can also determine the fetus' gender by looking at the XY / XX chromosomes.

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.
