The process of differentiation is mediated by signals that activate cell-type-specific genes in different cells.Answer and Explanation: Hox genes, or homeotic genes, are essential to the development of different body parts. They are expressed in a band-like pattern, and different Hox......
What is a mutation and why is it important to evolution? What is a gene pool? Why is it important to our study of evolution? Can you explain how homologous and vestigial structures might be explained other than as a result of evolutionary descent with modification? Hox genes are import...
Why are genes so important in terms of cell diversity? What is a gene? Explain in detail. How would a genetic mutation affect our evolution? Explain at least three ways that selection can preserve genetic variation. (a) Describe the advantages of genetic variation within a species population....
Are environmental changes in DNA heritable? Why does this question matter? 100-150 words Explain whether a mutation affects the organism itself or the organism's offspring. A developmental change that would have been caused by genes other than Hox genes is what? What is epigenetic regulation o...
What are the similarities and differences between microevolution and macroevolution? Why do all animals, both vertebrates and non-vertebrates, share the same hox genes? Explain the different types of mutations that occur: missense point mutation, silent point mutation, frameshift nons...
Why do humans have some genes in common with bacteria, more genes in common with fish, and even more genes in common with mice? Why are these genes similar but not identical? Explain. Evolution ...
In evolution, passing genes on to future generations is what determines fitness. If an organism has thousands of offspring, but they all die before...Become a member and unlock all Study Answers Start today. Try it now ...
Considering the Giraffe and Okapi, what other organisms do they seem to be related to? Explain using anatomy, embryology, molecular biology, etc.Mammals:Mammals are defined as the group of vertebrate animals that includes all mammals, ...
