During inter-phase of cell division, the genetic material is duplicated to allow for division into 2 identical daughter cells. The tumour suppressor gene checks for errors in the DNA, and if found, apoptosis (cell death) is initiated by p53 protein. The pRb (retinoblastoma) protein stops the progression of the cell cycle form G0 into S phase if the cell division is complete hence stemming unregulated cell division.
Explanation:
food chain shows only one possible feeding pathway while food web shows numerous feeding pathway
When completing Punnett Squares, you cross the letters that meet up. For example, their are two TTs and two Tts. Dominant will always show before a recessive so if it's TT or Tt it will be the dominant version. two tt's mean that it's recessive. In a Punnett Square, one box = 25%.
Part A: The genotypic ratio is 50% TT and 50% Tt. The phenotypic ratio is 100% tall.
Part B: The two Tt's could produce a short plant because there is a 25% that the parents will both give t's.
