- Discuss Concepts Arguably, in sexually reproducing animals, development begins when eggs and sperm form in the parents. In a paragraph, explain the rationale for this idea.arrow_forwardDiscuss Concepts Experimentally, it is possible to divide an amphibian egg so that the gray crescent is wholly within one of the two cells formed. If the two cells are separated, only the cell with the gray crescent will form an embryo with a long axis, notochord, nerve cord, and back musculature. The other forms a shapeless mass of immature gut and blood cells. Propose an explanation for these outcomes.arrow_forwardDiscuss Concepts Developmental biologist Lewis Wolpert once observed that it is not birth, marriage or death, but gastrulation which is truly the most important time in your life. In what sense is he correct?arrow_forward

Explain.arrow_forwardMatch the following some are redundant please explain why?: Axis specification Pattern formation Genes encoding Nodal signnaling pathway members. Achondroplasia A gene which when present on th X chromosome due to a translocation cause 46, XX Differences in sex development. Organogenesis A family of genes which are found in 4 clusters of several related genes on the hiuman chromosomes . Genes which are found on the chromosomes in the same order as their expression pattern along with anterior-posterior axis in the early vertebrate embryo. HOX genes SOX9 SRY Cells moving and changing shape to form the alveoli of the developing lung Mutations in these genes can cause congenital heart defects PAX6 Establishing which cells will later become each of the different parts of the eye Establishing which cells in the early embryo will develop into the front or the back A condition caused by mutations in a gene encoding a FGF receptor Pax genesarrow_forwardGradients of morphogens can be preestablished in the oocyte. Also, later in development, morphogens can be secreted from cells. How are these two processes similar and different?arrow_forward
- Cleavage divides the eggs of vertebrates and many other animals into a cluster of separate cells. By contrast, theequivalent stage in the Drosophila embryo generates a syncytium. How does the presence of a syncytium affectthe early development of Drosophila?arrow_forward5. Provide three differences of the endodermal parts of the 72-hour chick embryo with the 10 mmpig embryo?arrow_forwardDiscuss the role of homeotic genes in development. Explain what happens to the phenotype of a fruit fly when a gain-of-function mutation in a homeotic gene causes the protein to be expressed in an abnormal region of the embryo. What are the consequences of a loss-of-function mutation in such a gene?arrow_forward
