Mendelian Genetics Worksheet: Understanding Genotype and Phenotype from Pea Plant Crosses, Study notes of Biology

This worksheet covers various concepts related to mendelian genetics, including the importance of genotype and phenotype, the results of pea plant crosses, and the law of segregation. Students are expected to answer questions about the number of genes in a gamete, the significance of a sample size in genetics, and the meaning of homozygous and heterozygous genotypes.
