Compare and contrast sexual and asexual reproduction.  Identify the most accurate statement.   a. Asexual reproduction results in more offspring per mother.   b. Sexual reproduction is always more costly.   c. Sexual reproduction is associated with an increase in homozygosity.   d. Asexual reproduction is always bad for a species.

The maintenance of sexual reproduction in populations is a challenge for evolutionary biologists. Explain the paradox of sex and identify reasons that sex is prominent in natural populations.

The survival and reproduction of young Lazuli buntings (birds) depends on the brightness of their feathers, which range from dull brown to bright blue. Juvenile birds with dull brown feathers are not attacked by adult birds and are able to obtain high quality territories and reproduce more. Juvenile birds with bright blue feathers are more attractive to mates and reproduce more when they become adults. However, birds with intermediate plumage are often attacked by adults and usually fail to reproduce. This is an example of what type of selection? Stabilizing Directional Disruptive Frequency-dependent Artificial

In humans, mammals and many other chordates sexual reproduction takes place by fusion of large immobile ovum and small motile sperm. This kind of sexual reproduction is: Select one: a. Isogamy b. Schizogony c. Oogamy d. Conjugation e. Polyteny

Homologous structures are those that share a similar origin, but may have different functions. Identify the homologous structures that exist between two reproductive systems.

Which of the following is INCORRECT regarding meiosis? Select one: O a. It provides for genetic variation in the offspring. O b. It occurs in most body cells at some time during the life of the individual. O c. It keeps the chromosome number constant from generation to generation. O d. It occurs only in species of organism that have sexual reproduction. O e. It halves the chromosome number in reproductive cells.
