Hope this helps BOI!!!
This has to do with SURFACE TO VOLUME RATIO. For a typical small cell, its surface area to the volume ratio get smaller as the cell grows. This implies that, if the cell grows beyond a certain limit, then the amount of nutrients that entered the cell will be limited, that is , nutrients will not be able to migrate into the cell as needed. To avoid this, the cell has to divide to reduce its surface to volume ratio.<span />
Answer:
The genotype of both parents is RrYy.
The possible types of gametes would be RY, Ry, rY, and ry.
The cross would produce offspring that can have one out of four types of phenotypes:
- Round and yellow seeds (1 RRYY+ 2 RrYY +2 RRYy + 4 RrYy) = 9/16
- Wrinkled and yellow seeds (3 rrYy) = 3/16
- Round and green seeds (1 RRyy + 2 Rryy) = 3/16
- Wrinkled and green seeds (rryy) = 1/16
Thus, one out of 16 offspring would have wrinkled and green seeds.
