Exercise 2
When working out genetics problems in this and succeeding chapters, always assume that members of the P 1 generation are homozygous, unless the information or data you are given require you to do otherwise.
Review the Chapter Concepts list. The first five concepts provide a modern interpretation of Mendelian postulates. Based on these concepts, write a short essay that correlates Mendel's four postulates with what is now known about genes, alleles, and homologous chromosomes.
CHAPTER CONCEPTS
▪Inheritance is governed by information stored in discrete factors called genes.
▪Genes are transmitted from generation to generation on vehicles called chromosomes.
▪Chromosomes, which exist in pairs in diploid organisms, provide the basis of biparental inheritance.
▪During gamete formation, chromosomes are distributed according to postulates first described by Gregor Mendel, based on his nineteenth-century research with the garden pea.
▪Mendelian postulates prescribe that homologous chromosomes segregate from one another and assort independently with other segregating homologs during gamete formation.
▪Genetic ratios, expressed as probabilities, are subject to chance deviation and may be evaluated statistically.
▪The analysis of pedigrees allows predictions concerning the genetic nature of human traits.
