The table above describes different types of chromosome disorders. which diseases are caused by an extra chromosome? a. down syndrome, turner's syndrome, klinefelter's syndrome b. edward's syndrome, down syndrome, klinefelter's syndrome c. cri-du-chat syndrome, turner's syndrome, klinefelter's syndrome d. edward's syndrome, cri-du-chat syndrome, turner's syndrome

The answer is (B) Edward's Syndrome, Down Syndrome, Klinefelter's Syndrome.

These syndromes are caused when there is an extra copy of chromosomes present in the cells.

In Edward's syndrome, there is an extra copy of the chromosome 18.

In Down's syndrome, there is an extra copy of chromosome 21.

In Klinefelter's syndrome, there is an extra copy of X chromosome.

the answer to your question is b

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.
