Bio 1001 Test 2 – 76 Questions on Meiosis, Genetics, Heredity & Disorders – LSUE

This document contains 76 fully solved questions and answers for Test 2 of the Bio 1001 course at Louisiana State University Eunice (LSUE) for the 2025/2026 academic year. It offers a detailed exploration of genetic and reproductive biology, focusing on meiosis I and II, gamete formation, chromosomal behavior, genetic recombination, and Mendelian genetics. Topics include genotype vs. phenotype, dominant and recessive traits, allele variations, and key cellular processes such as synapsis and chromatid crossover. The guide also covers a wide range of inherited disorders and chromosomal abnormalities, including cystic fibrosis, Tay-Sachs, phenylketonuria (PKU), sickle cell anemia, hemophilia, Turner syndrome, Klinefelter syndrome, trisomy, monosomy, mosaicism, and other forms of aneuploidy. Concepts in epigenetics and gene expression are also briefly introduced. Each question is structured for maximum clarity, with concise answers that follow the tested curriculum. This study material is highly relevant for students enrolled in introductory biology, human genetics, life sciences, allied health, nursing, medical assisting, and pre-medical programs. It’s particularly beneficial for those preparing for exams involving genetic inheritance, meiosis, hereditary diseases, and molecular biology. The Q&A format ensures quick learning and effective test preparation.
