Question
Parallelism in development O A is a method of gene duplication. B.was advocated by von Baer. Crefers to the colinearity of Hox genes Dwas the idea that developmental stages progress from the simple to the complex, reflecting the scala naturae. QUESTION 4 Which of the following is an important evolutionary implication of a gene having many regulatory enhancers? a. The primary control point at which gene expression is regulated is initiation of translation, so enhancers do not play a significant role in evolution. b Regulatory enhancers can increase morphological variation within a population and hence the amount of variation that natural selection has to act on. c.Current experimental data do not indicate evolution in regulatory enhancers. d.A single gene can have numerous regulatory enhancers associated with it, but these regulators can produce only small variations in gene expression. QUESTION 5 What are the three possible fates of paralogs? Acreate a new function B.become duplicated C.create subfunctionality Denhance gene expressionExplanation / Answer
yes, these are the correct answers........
Parallel evolution refers to the evolutionary process wherein two or more species in the same environment develop similar adaptation or characteristics. Example of parallel evolution: North American cactus and the African euphorbia that developed similar adaptation, which is their thick stems and sharp quills to survive the hot, arid climates.
