Problem: Mendel conducted experiments on pea plants, which led to the understanding of dominant vs recessive genes. Dominance is the phenomenon where a dominant allele masks the effects of the other allele. The recessive trait was only seen in cases where the plant had two recessive alleles. Homozygous traits are two alleles of both either dominant or recessive, while heterozygous traits are one dominant and one recessive allele. This led to the understanding of genotypes, which are the different alleles in a particular gene, and phenotype, which are the observable characteristics such as height. Use the above information along with the diagram to answer the question: If all of the F1 generation are yellow, how is there a green in the F2 generation? All of the F1 generation are heterozygous The green is a result of genetic mutation The green allele skipped a generation All of the F1 generation are homozygous
