For the following statements, determine if the statement is true or false. If False, change the underlined word to make it true.
_____________________47. The main purpose of meiosis is to make cells that are genetically identical to the parent cells
_____________________48. Spermatogenesis causes the production of 1 egg and 3 polar bodies
_____________________49. A zygote forms when a sperm joins with an egg.
_____________________50. Cell divide by mitosis if identical copies of the parent cells are needed
_____________________51. Meiosis can happen everywhere in males
_____________________52. When two haploid cells join, they can make a diploid cell.
_____________________53. Crossing-over happens at specific locations each time.
_____________________54. The symbol for diploid is n
_____________________55. Gametes are diploid
