That substance was most likely parathyroid hormone.
<h3>What is a parathyroid hormone?</h3>
It should be noted that the parathyroid hormone is the hormone that is released to control calcuim levels in the blood.
In this case, this is illustrated as the blood calcium levels were above normal and the pathologist found cancer cells that produced a hormone-like substance.

Answer:
The answer is 300.
Explanation:
When we cross GG and gg, 100% of the offspring will be heterozygous. If the heterozygotes show 75% penetrance meaning that there is a 75% probability that the plant that has the G gene will actually show it in it's phenotype.
So that means that 75% of the offspring should have dark green color, which means that 300 plants will have the expected phenotype and 100 will not.
I hope this answer helps.
Go online and look up ressesive and dominate Gene's and Gregory Mendel he crossbreed plants such as what you have described and have found some interesting results that do include your red and white crossbreeding to create pink. this is usually called a Punnet Square.
dominate gene
Red = R
White = W
recessive gene
Red=r
White = w
pink is either a mixture of recessive and dominant Gene's or one dominant and one recessive
