The following Punnett Square is a monohybrid cross. It takes the genotypes of the parents and predicts the genotypes of their offspring. Fill in the punnett square. Each square will have 2 letters

For the 1st block on the left I think there are 2 dominants for that would be BB. The 1st block on the right would be 1 dominant and 1 recessive and that would be Bb. The bottom on the left would be the same as the first block on the right. That would be Bb. The last block that would be the bottom right would be 2 recessives and that would be bb. I hope this might help.

Explanation:

When you are doing punnet squares, you have dominant and recessive traits. There are ways you can do that. If you have 2 alleles of each parent of that offspring, there will be a genotype and a phenotype that represents a genetic trait of each genotype. I hope this helps your question.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
