Summary Introduction

To determine: The policies to be promoted in order to reduce the incidences of prematurity and/or low birth weight.

Introduction: When a baby is born at a gestational age of less than 37 weeks, it is known as premature birth. Premature babies are seen to have complications during their birth as the organs may not be completely developed to be fully functional. Mental retardation is one of the pathological conditions seen in premature babies. Other respiratory, cardiovascular, and gastrointestinal problems may also be associated with premature babies.

Summary Introduction

To determine: The policies to be promoted in order to reduce malformation of birth.

Introduction: Malformations of birth refers to the medical conditions that are present at the birth of a child. The malformation or defects may be physical or intellectual. Developmental malformation is also seen. Child having a birth defect either has problems with the shape of an organ or a body part or the way an organ works.

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.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
