Chapter 3, Problem 16P
Summary Introduction

a.

To determine:

Whether progeny will be produced or not for the cross ♂ S1 S2 × ♀ S1 S2 and list all possible genotypes of these progeny if they are produced.

Introduction:

Cross is the breeding of two parents that produces an offspring that will contain the genetic material from each of the parent. The genetic material that passes from parents to offspring is DNA.

Summary Introduction

b.

To determine:

Whether progeny will be produced or not for the cross ♂ S1 S2 × ♀ S2 S3 and list all possible genotypes of these progeny if they are produced.

Introduction:

The set of the morphological characteristics of an organism that results from the interactions of the genes is known as the phenotype of the individual. For example, in pea plants, tallness is a phenotypic trait.

Summary Introduction

c.

To describe:

Whether progeny will be produced or not for the cross ♂ S1 S2 × ♀ S3 S4 and list all possible genotypes of these progeny if they are produced.

Introduction:

The set of the alleles in DNA that carries the information for the expression of a trait in an individual is known as its genotype. For example, genotype ‘TT’ expresses the tallness in plants.

Summary Introduction

d.

To describe:

The ways by which the mechanism of incompatibility prevents self-fertilization.

Introduction:

During the process of translation, exons or its some portion within a pre-mRNA transcript are removed, which results from encoding different protein sequences from a single gene.

Summary Introduction

e.

To describe:

The ways by which it is ensured by the incompatibility system that all plants for different alleles of the S gene would be heterozygous.

Introduction:

According to Mendel's conclusion, a pair of factors control the expression of a trait (a term that was used by Mendel for genes), and each factor of the pair segregate from each other during gamete formation.

Summary Introduction

f.

To describe:

The reason for peas to be not governed by this incompatibility mechanism.

Introduction:

Gregor Mendel conducted experiments for many years using pea plants. Mendel analyzed his results quantitively and concluded that traits transferred from one generation to another generation

Summary Introduction

g.

To describe:

The reason for favoring the emergence of new incompatibility alleles by evolution and making the gene increasingly polymorphic in populations of tomatoes or petunias.

Introduction:

Evolution is the process of heritable changes in the biological populations over successive generations, and these changes are the result of the expression of genes, that are inherited from parent to offspring during reproduction.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
