a. To determine: The reason for the fact that environmental similarity for monozygotic twins not being significantly different from that of the similarities for fraternal twins is important for heritability calculations. Introduction: Environmental conditions affect the inheritability of traits in populations. The similarity of traits in twins is affected by environmental conditions. Children being brought up in the same family share the environmental conditions.

To determine:

Whether MZ or DZ twins would be more useful to study for determining the heritability of a particular-trait in humans.

Introduction:

Traits of organisms can pass from the parents to their offspring, and this mechanism is known as an inheritance. Gregor Mendel was a monk, and he discovered three laws that describe the inheritance of factors from parents to offsprings.

Students have asked these similar questions

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.
