Anatomy and Physiology : Human Genetics

Human Genetics: Things You Should Know (Questions and Answers) explains the principles of heredity, chromosomes, and genetic variation in a question-and-answer format.

The book introduces chromosomes, genes, alleles, genotypes, and phenotypes, showing how hereditary traits are transmitted from one generation to the next. It describes autosomes and sex chromosomes, dominant and recessive alleles, homozygotes, heterozygotes, codominance, and incomplete dominance.

Key topics include mutations, polygeny, point mutations, crossing-over, and genetic recombination. The text also explains genetic disorders such as albinism, hemophilia, Klinefelter syndrome, trisomy 21 (Down syndrome), trisomy 13, and trisomy 18, along with how these conditions arise from chromosomal abnormalities.

The processes of mitosis and meiosis are described, along with their importance for cell division, reproduction, and the transmission of genetic information. Blood groups, carriers of genetic conditions, and X-linked inheritance are also explained.

This book will interest students, health science learners, and general audiences who want to learn about human genetics, its principles, and its role in health and disease.
