Mendelian Genetic problems

Could you please take a look at the attached problems that I have done which include Punnett square and genotype. I think I have done the problems correctly but I just need a second set eyes to see if there are any holes in my understanding on this topic.

Mating types and possible genotypes from different pairs of factors

How many different types of mating are possible a) from a single pair of factors. b) from two pairs of factors. c) from n pairs of factors.

When 3 pairs of factors are considered simultaneously.

Estimate the different mating types possible when 3 pairs of factors are considered simultaneously.

Determining the different types of gametes in individuals.

Enlist the different types of gametes produced by the following individuals: 1. AABBCc 2. aaBbCc 3. AaBbccDd

Predicting the phenotypes and genotypes from crosses of squash.

Predict the results of the following crosses: a) Tall [dominant and homozygous] with dwarf - F1? b) Product of selfed F1. c) F1 with original tall parent. d) F1 with original dwarf parent
