Explain how spermatogenesis is very sensitive to temperature.
What is in order for the process to occur, it needs to be 2 degrees below the normal body temperature for the organism. So for us, 98.6 is normal, 96.6 degrees is optimum temperature for spermatogenesis to occur. Hence this the reason testes are located outside the body, away from body heat.
400
In terms of our complementary base pairs of DNA, what does complementary mean?
What is it means that they only join with a specific one..Example: Adenine only binds with Thymine

Test to detect Down syndrome and Klinefelters's syndrome?
What is Amnicentesis. big needle is inserted into the pregnant woman to puncture and aspirate amniotic fluid, that fluid is used to make a karyotype to detect any anomalities.
