1) How species emerge/are defined
2)How new traits become fixed in a population/how new traits define a population
Homework Answers
Answer 1. Species is a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. Emergence of species as distinct and relatively homogeneous groupings of individuals is a consequence of the nonlinear dynamics inherent in sexual reproduction.
Answer 2. Trait of any species is specific to that species only and traits are carried from generation to generation form the transfer of gene from parent to off-spring. Traits are associated on the alleles that are found on genes. A fixed allele is the only variant that exists for that gene in the species. A fixed allele is homozygous for all members of that species.
New traits can come from transfer of genes between populations, as in migration, or between species, in horizontal gene transfer. Apart from this new trait in a species can come from mutations, natural selection, genetic drift, genetic hitchhiking, and gene flow.

Suppose species 1, 2, and 3 are endemic to a group of islands (such as the Galápagos) and are all descended from species 4 on the mainland (which will serve as an outgroup; its very large population size means that no new mutations have become fixed in its population in the time since the islands were colonized). We sequence a gene and find ten nucleotide sites that differ among the four species (among many other loci that do not vary)....

1. Describe how new alleles show up in a population. 2. Describe the difference between the term ‘theory’ when it is used in everyday language, and how it is used in scientific context. 3. Explain why mutations do not happen in response to changes in the environment. 4. Traits are not ‘magically’ given to organisms. Explain how the genetic variability in the population can result in a given trait becoming common in that population. 5. Fitness is a difficult concept...

Question 1: Antibiotics are effective against a population of bacteria. However, you observe a new resistance allele arises in the bacteria population. You observe the fitness of the mutant is 1% higher than the wild type and the population size (N) of the bacteria is 106. A) How long does it take for the resistance allele to reach fixation? Hint: The fixation time is defined as the time from a single copy of the resistance allele (1/N) to near fixation...
