Genetic Traits Review: Understanding Dominance and Ratios in Inheritance

This review delves into key genetic principles as presented by Dr. Lamia, focusing on the inheritance patterns of dominant and recessive traits. We explore the specific examples of traits represented by the alleles T (tall) and t (short), discussing their combinations and outcomes. The review highlights the expected phenotypic ratios in offspring, illustrating how dominance affects trait expression. Genetic terminology is clarified, ensuring a solid understanding of concepts such as homozygous and heterozygous genotypes.
