Answer:
27 genotypes and 8 phenotypes
Explanation:
Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:
I add an image where you can see all the 27 genotypes and frequencies.
Finally, all the 8 phenotypes with the following frequencies:
27/64 A-B-D-
9/64 A-B-dd
9/64 A-bbD-
9/64 aaB-D-
3/64 A-bbdd
3/64 aaB-dd
3/64 aabbD-
<u>1/64 aabbdd </u>
Total 64/64
Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)

Answer:
How do limiting factors affect population size?
Explanation:
Limiting factors are factors that affects the size of a population and slows down its growth rate or stop it in its entirety.
These factors include food, space, temperature, sunlight etc.
Limiting factor like food can affect a population greatly like not having enough preys in a forest, therefore the predators are starved to death or even in a fish pond where there is high competition for space (overpopulated) which leads to oxygen deficiency i.e they compete for oxygen as well, and this can lead to death as well.
