Chapter 9, Problem 12SA
Summary Introduction
To Analyze: The reason why more closely located genes are not inherited independently.
Introduction:
Gene can be defined as the basic functional and physical unit of heredity. They are generally made up of DNA (deoxyribonucleic acid). DNA contains information to generate proteins and other required data.

- Suppose that a grandfather, mother, and son all have the same homozygous dominant genotype for a gene that controls facial hair growth. The grandfather and son have thick beards, but the mother has no significant facial hair. What type of non-Mendelian inheritance is this? O a) Sex-influenced inheritance Ob) Sex-limited inheritance Oc) Onset of genetic expression O d) X-linked dominant inheritancearrow_forwardYou are a gene hunter, trying to find the genetic basis for a rare inherited disease. Examination of six pedigrees of families affected by the disease provides inconsistent results. For two of the families, the disease is co-inherited with markers on chromosome 7. For the other four families, the disease is co-inherited with markers on chromosome 12. Explain how this difference might have arisen.arrow_forwardWhich of the following describes the difference between genetic maternal effect and cytoplasmic inheritance? O Progeny from a Genetic Maternal Effect cross express the phenotype of their mother's genotype, while progeny from a cytoplasmic inheritance cross share a genotype and phenotype of their mother. Progeny from a Genetic Maternal Effect cross have a phenotype that reflects their own genotype, while progeny from a cytoplasmic inheritance cross share a genotype and phenotype with their mother. Progeny from a Genetic Maternal Effect cross have the same genotype as their mother, while progeny from a Cytoplasmic Inheritance cross do not. There is no difference.arrow_forward
