{"product_id":"b0h9wvqr8t","title":"Challenging Numerical Problems in Biology - 300 Problems in Genetics: Covering Mendelian Inheritance, Probability, Pedigree Analysis, Blood Groups, ... Population Genetics \u0026 Genetic Disorders","description":"\u003cp\u003eGenetics often begins with ideas that seem straightforward: genes are inherited, alleles separate during gamete formation, dominant and recessive traits follow recognizable patterns, and chromosomes carry hereditary information from one generation to the next. The difficulty often appears when those ideas are converted into numbers.\u003cbr\u003e\nA question may ask for the expected number of offspring with a particular phenotype. Another may require the probability of two independent genetic events occurring together. A pedigree may hide an unknown genotype across several generations. A gene-mapping problem may provide recombinant offspring and ask for recombination frequency or map distance. Population genetics introduces another layer, where allele frequencies, genotype frequencies, carrier proportions, and equilibrium calculations must all be connected correctly.\u003cbr\u003e\nThis workbook approaches genetics through numerical problem solving.\u003cbr\u003e\nAcross  300 practice problems , readers work with the calculations and reasoning that appear throughout classical genetics, transmission genetics, and population genetics. The problems are organized into ten focused areas:  Mendelian inheritance, monohybrid and dihybrid crosses, probability in genetics, pedigree analysis, blood groups, sex-linked inheritance, gene mapping, Hardy-Weinberg equilibrium, population genetics, and genetic disorders .\u003cbr\u003e\nThe opening problems establish the numerical foundations of inheritance. Readers work with dominant and recessive alleles, genotype and phenotype ratios, testcrosses, incomplete dominance, and codominance. Familiar ratios such as 3:1, 1:1, and 1:2:1 are treated not simply as facts to remember, but as proportions that must be translated into expected numbers.\u003cbr\u003e\nThe problems then move into monohybrid and dihybrid crosses. Independent assortment introduces the familiar 9:3:3:1 relationship, while gene interactions require careful interpretation of modified ratios such as 9:7, 9:3:4, 12:3:1, and 15:1. These exercises encourage readers to identify the genetic rule before beginning the arithmetic.\u003cbr\u003e\nProbability forms another major part of genetics. Addition and multiplication rules, conditional reasoning, independent events, and combined inheritance probabilities are applied to genetic situations. Instead of treating probability as separate mathematics, the problems show how it operates inside inheritance questions.\u003cbr\u003e\nLater chapters extend the numerical work into pedigrees, blood-group inheritance, and sex-linked traits. Readers interpret family relationships, infer possible genotypes, calculate inheritance probabilities, and distinguish autosomal patterns from sex-linked transmission.\u003cbr\u003e\nGene mapping introduces recombination frequency, linkage, map distance, and the interpretation of offspring classes. Hardy-Weinberg problems move from individual crosses to populations, using allele frequencies and genotype frequencies to examine genetic structure. Population genetics problems further explore how frequencies may change through evolutionary processes and population-level forces.\u003cbr\u003e\nThe final section applies numerical reasoning to genetic disorders and inherited risk scenarios. These problems are educational exercises designed to develop calculation and interpretation skills, not tools for personal medical prediction or genetic counseling.\u003cbr\u003e\nEach problem is accompanied by a worked solution so readers can compare not only the final numerical answer but also the reasoning used to reach it. A useful approach is to attempt each problem independently, write down the genotypes and governing genetic principle, perform the calculation, and only then consult the solution.\u003cbr\u003e\nGenetics becomes far more manageable when the numbers are approached systematically. These 300 problems provide repeated opportunities to turn inheritance principles into calculations, test assumptions, interpret results, and develop a more disciplined approach to numerical genetics.\u003c\/p\u003e","brand":"ANT","offers":[{"title":"Ebook","offer_id":67924064502005,"sku":"YSL51139","price":5.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/8774\/8597\/files\/614Ce4FgWdL._SY1500.jpg?v=1793672433","url":"https:\/\/www.newbooks.store\/products\/b0h9wvqr8t","provider":"NewBooks","version":"1.0","type":"link"}
