Chapter 3, Problem 1QP

a.

Summary Introduction

To determine: The differences between gene, allele, and locus.

Introduction: The genotype is the genetic constitution of the organism while the phenotype refers to external characters visible in an organism.

b.

Summary Introduction

To determine: The differences between the genotype and phenotype.

Introduction: When the alleles inherited by the zygote are same then the genotype of the individual is called homozygous whereas, when the zygote inherits two different alleles it is called heterozygote.

c.

Summary Introduction

To determine: The differences between dominant and recessive.

Introduction: The alleles are the two contrasting variants of characters controlled by a specific gene. These alleles are distributed into the gametes during meiosis and then combined in a zygote during fertilization.

d.

Summary Introduction

To determine: The differences between complete dominance, incomplete dominance, and codominance.

Introduction: Gregor Mendel was an Austrian monk, who worked on a pea plant to observe the pattern of inheritance of certain characters from the parent plant to the offsprings. He termed genes as factors that were passed from one generation to another. He proposed three laws which came are known as Mendel’s law of genetics.

Mendel's concept of dominance states that in a genotype where two different alleles of a locus are present, only the trait encoded by the dominant allele is observed. Give a molecular explanation for dominance, i.e. explain intracellular molecular events that can result in what we observe as dominance on a phenotypic level. Use the gene that encodes seed shape in peas as an example, where roun(R) is dominant over wrinkled(r), to explain how RR and Rr plants can have the same phenotype.
Chi-square Test In the pea plants use by Gregor Mendel in his study, the purple flower color is dominant over white,and the axial position on a branch is dominant over terminal. A plant believed to be heterozygouswas selfed and produced flowers with the following phenotypes: 23 white terminal68 white axial81 purple terminal187 purple axial a. assign alleles to the different traitspurple __________ axial ___________white ___________ terminal _______ b. refer to the image attached
Working with the definitions of penetrance and expressivity, analyze the following pedigree and assume that the father of the proband is homozygous for a rare trait. (Consider a rare trait here to be less than 1 in 30,000.) What pattern of inheritance other than autosomal recessive could explain this pedigree? In particular, explain the genotype and phenotype of the proband (arrow).
