Predict whether pre-zygotic isolation is more likely to occur in sympatry or allopatry and explain why.
Answer
Pre zygotic isolation is more likely to occur in sympatry it is due to reinforcement as reinforcement model states that as the time of evolution post zygotic barriers arise first due to the isolation of population in divergence manner. If they rejoin again then they still interbreed between themselves but their hybrids have a lower fitness. So according to the selection for reproductive isolation so selection has been taken place which is reinforced in divergent direction.
Predict whether pre-zygotic isolation is more likely to occur in sympatry or allopatry and explain why.

Come up with a hypothesis why a certain mutation is more likely to occur in male meiosis or female meiosis. Consider the differences between male and female meiosis and how point mutations, inversions, or deletions can occur.
1) Where are deletions most likely to occur in this dystrrophin gene? 2) Explain why elevated blood creatine kinase levels are a good proteomic marker for Duchenne muscular dystrophy. 3) Why is it more difficult to screen females for variants in the dystrophin gene? 4)In a muscle cell, where is the dystrophin protein located?
Which of the following mutations are more likely to occur based
on their codons, group classifications, and structures?
4) (20 points) Which of the following mutations are more likely to occur (aka more conservative) based on their codons (show the codons and underline anysingle nucleotide changes), group classifications, and structures (draw or describe the structures)? Circle or underline the mutation you believe is more conservative and explain your choices. BE SURE TO EXPLAIN WHY THE LESS CONSERVATIVE MUTATION IS LESS...
