Sex-Linked and Recessive Traits
Sex-linked traits are inherited via the sex chromosomes, with many carried on the X chromosome. These traits often show different patterns in males and females, as males have only one X chromosome. Recessive traits, meanwhile, are expressed only when an individual has two copies of the recessive allele. The guide explains how to identify and predict these traits using Punnett squares and pedigree analysis. It also covers how sex-linked recessive conditions, like color blindness, are more common in males. Understanding these concepts is crucial for solving genetics problems on the Biology EOC exam, and the guide provides clear examples and practice questions to master them.
Codominance and Incomplete Dominance
Codominance occurs when both alleles are expressed equally in the phenotype, such as in blood type AB, where both A and B antigens are present. Incomplete dominance shows a blending of traits, like pink flowers from red and white parents. These concepts challenge Mendel’s simple dominance model. The guide explains how to identify and predict these traits using Punnett squares, with examples like snapdragons and four-o’ clock plants. Understanding these patterns is essential for solving genetics problems on the EOC exam, and the guide provides practice questions to reinforce these concepts and ensure mastery of non-Mendelian inheritance.
Genotypic and Phenotypic Ratios
Genotypic and phenotypic ratios are fundamental in understanding inheritance patterns. The genotypic ratio represents the proportion of different genotypes in offspring, while the phenotypic ratio reflects the observable traits.

Evolution and Natural Selection
This section explores the mechanisms driving evolution, including natural selection, genetic drift, and speciation. It provides insights into evidence supporting evolutionary theory, helping students grasp how species adapt and diversify over time.
Mechanisms of Evolution
The mechanisms of evolution are fundamental processes that drive biological change over time. Natural selection, genetic drift, mutation, and gene flow are key drivers. Natural selection favors traits that enhance survival, while genetic drift alters allele frequencies randomly. Mutations introduce new genetic variation, and gene flow transfers alleles between populations. These mechanisms collectively shape biodiversity and adaptation. Understanding them is crucial for grasping evolutionary principles and excelling in the Biology EOC exam; This section provides detailed explanations and examples to help students master these concepts and apply them to real-world scenarios effectively.
Evidence for Evolution
The evidence for evolution is vast and comes from multiple fields of study. Fossil records show a chronological progression of life forms, with transitional fossils linking species. Comparative anatomy reveals homologous structures, like forelimbs in vertebrates, indicating common ancestry. Molecular biology demonstrates genetic similarities, such as shared DNA sequences across species. Biogeography explains geographic distributions, like similar species in isolated areas. Additionally, observable evolutionary changes in populations, such as antibiotic resistance in bacteria, provide direct evidence. These lines of evidence collectively support the theory of evolution, offering a well-rounded understanding of how life has diversified over time.
Speciation and Phylogeny
Speciation is the process by which new species emerge, often due to reproductive isolation. Mechanisms include geographic barriers, genetic drift, and selection pressures. Phylogeny studies evolutionary relationships, represented in tree-like diagrams. Molecular data, fossils, and comparative anatomy help reconstruct these histories. Key concepts include homologous structures, analogous traits, and vestigial features. Understanding speciation and phylogeny explains biodiversity and the interconnectedness of life forms. For example, the Galapagos finches illustrate adaptive radiation, while horse evolution shows gradual changes over time. These principles are crucial for tracing life’s history and understanding how species diverge and adapt to their environments.
