Dominguez et al. (2004) suggest that by studying genes that determine growth and tissue specification in the eye of Drosophila, much can be learned about human eye development.

(b) What evidence indicates that the eyeless gene is part of a developmental network? (c) Are genetic networks likely to specify developmental processes in general? Explain fully and provide an example.

Wyckoff et al. (2000. Nature 403:304-309) have proposed that some human male reproductive-associated genes have evolved by natural selection and not by neutral evolution. Part of the DNA sequence results of their study is shown below. Which gene(s) did seem to evolve by natural selection? Note: dn = number of substitutions per non-synonymous (replacement) sites and ds = number of substitutions per synonymous (silent) sites. dn ds Acrosin-Trypsin 0.138 0.064 Protamine 1 0.133 0.046 SRY 0.055 0.090 Histone H1 (testicular) 0.055…
1. Is there a correlation between survival, reproduction and environment color? Explain. 2. Are there any other factors besides color important in determining survival in the simulation? 3. Why did we set the rate of reproduction at 2/survivor? What would happen if one color always had more offspring than other colors? 4. Suppose that a mutation occurs and a white, “albino” bead is born. How well would it survive in your environment? Please answer all questions please
13. Mr. Santos is a Developmental Biologist, wants to study the growth and development of the three animals namely: reptiles, birds, and mammals. He found out that during their early stages of development, the embryos of reptiles, birds, and mammals look very similar. Which of the following is the BEST hypothesis for his data gathered? * a. They have common ancestors. b. They live in the same type of environments. c. They have undergone parallel evolution. d. They are no longer undergoing evolution. 14. Charles Darwin is considered as the father of evolution where he published a book called, “On the Origin of Species by Means of Natural Selection”. This book contains many features regarding the evolutionary changes in an organism. All of the following are situations related in his book EXCEPT: * a. If people from the other regions will migrate to Metro Manila, the food supply will not be enough to support the Population…
