The linkage in the three loci and their map distances. . Introduction. Linkage is the phenomenon in which two or more genes are linked to each other being present very close to each other on the chromosome. This causes the genes to prevent crossing over and pass on as wild state from parent to offspring.

To determine: The linkage in the three loci and their map distances. .

Introduction. Linkage is the phenomenon in which two or more genes are linked to each other being present very close to each other on the chromosome. This causes the genes to prevent crossing over and pass on as wild state from parent to offspring.

b.

Summary Introduction

To determine: The allele arrangement on the chromosomes of the triple heterozygote used in the testcross.

Introduction. Recombination is the process that is exclusive to the meiotic division as it allows the exchange of genetic material between the non-homologous chromosomes. The recombination process is responsible for the shuffling of the characters and producing a zygote that is different from both the parents but have the chromosomes from both the parents.

c.

Summary Introduction

To determine: The value of interference.

Introduction: The law of independent assortment was given in a dihybrid cross which is the cross between the alleles of two pairs of contrasting characters. The alleles produced by each character are independent to combine with the alleles of the other character. This independent sorting of the alleles irrespective of the dominant or the recessive trait is defined as the law of independent assortment.

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.
