The pattern of embryonic cleavage peculiar to a species is determined by two major parameters: 
(1) the amount and distribution of yolk protein within the cytoplasm, which determine where cleavage can occur and the relative sizes of the blastomeres
(2) factors in the egg cytoplasm that influence the angle of the mitotic spindle and the timing of its formation

Which of the following statements is incorrect about patterning of embryonic cleavage?

#Unit 5. Developmental Biology
  1. Species having Isolecithal egg follow a holoblastic cleavage in which cleavage furrow extends through the entire egg
  2.  Species having mesolecithal egg follow a meroblastic cleavage in which cleavage furrow cleaved only a portion of the cytoplasm
  3. species having telolecithal egg follow a meroblastic cleavage that is incomplete cleavage
  4. Species having centrolecithal egg follow a meroblastic cleavage in which cleavage furrow cleaved only a portion of the cytoplasm and does not penetrate the yolky portion
