Unprotected Cohesins Answer: Proteins that hold homologous
chromosomes together
Spermatogenesis Answer: Meiosis in males
Oogenesis Answer: Meiosis in females
Zygote Answer: The conjunction of the sperm and the egg
Dizygotic Twins Answer: Non-identical twins
Two eggs released and fertilized at the same time
Each embryo has a separate placenta and extraembryonic membrane
(eventually fuse together)
Monozygotic Twins Answer: Identical Twins
Made by splitting at the 2 cell stage
The inner cell mass splits and the 2 embryos share a common
extraembryonic membrane and placenta
