Please help me on both questions. i don’t know at all and i’m so confused

cant really answer much since you need the class results for these. but i can simplify question 1. so, does the class results prove that the traits made my dominant alleles are the most common? or in other words, are traits made  by dominant alleles most common in the class results?

number 4 is yes because there are more possibilities that the dominant trait will occur than the recessive trait. therefore, it is more common and the conception is correct

i don't know what the picture looks like but i can take a guess and say maybe basidiomycetes?

your answer should be c) enjoy!
