 Which of the following statement is correct regarding mammalian cleavage?

#Unit 5. Developmental Biology
  1. In all mammalian embryos, the first cleavage is a normal meridional division; however, in the second cleavage, one of the two blastomeres divides equatorially and the other divides meridionally.
  2. Mammalian embryos increase exponentially from 2 to 4 to 8 cells, but frequently contain odd numbers of cells.
  3. Mammalian genome is inactivated during early cleavage and zygotically transcribed proteins are necessary for cleavage and development.
  4. Maternally encoded proteins can persist through most of the cleavage stages and play important roles in late stages of development.
