How is plant cell cytokinesis different from animal cell cytokinesis?

#SCPH01 Biochemistry
  1. The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins.

  2. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

  3. The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells.

  4. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.

#SCPH06 I Botany

Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?

A plant height in Maize is control by 3 pair of polygene .Two varieties of maize averaging 120 and 60 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 40 inches in height. What is proportional of F2 progeny that is display phenotype either 120 cm or 60 cm height?
