28. SO IN CONCLUSION, meiosis is a process that ______________ the
chromosome number so that you can get ready to produce a
_____________________. This process is necessary, because everyone knows
that when you produce a ________________ each parent contributes
_______________ of the genetic information. Since this process is leading up to
a zygote (which is a __________________ __________) it would have to be
occurring inside of the female’s ________________ and inside of the male’s
_____________. The chromosome number in these organs is originally
___________ (#) which is the ________________(diploid/haploid?) number.
Meiosis reduces the number of chromosomes to the number _______________
(in humans) which is the _______________ (diploid/haploid?) number. Once the
egg and sperm find each other in the process of ________________ they produce
a z_______________ which returns the chromosome number to
______________ which is the _________________(diploid/haploid?) number.
This process is amazing, NO??????
