B is correct because
Under the Red Queen hypothesis, sexual reproduction gives an advantage over asexual reproduction because sexually reproducing organisms 'shuffle' their genes during sex cell formation and fusion of sex cells from two individuals," says Soper. "This means that the resulting offspring of sexually reproducing individuals may have an increased likelihood of escaping infection due to the production of unusual genetic backgrounds.

According to an idea called the Red Queen hypothesis, sexual reproduction is favored over asexual reproduction when pathogens are present because it increases genetic diversity, allowing some of the host offspring to escape the pathogen. Some researchers were interested in testing this idea in aphids which can reproduce both asexually and sexually. In this study, the researchers measured rates of fungal infection and frequency of sexual reproduction across many populations to see if these two variables were related. It was...

2. Morran et al. 2011 tested the Red Queen Hypothesis with an experiment on populations of the roundworm Caenorhabditis elegans. Populations of C. elegans include both males and "hermaphrodites" (individuals capable of producing both male and female gametes). Hermaphrodites can reproduce alone (termed selfing i.e., asexual reproduction) or mate with males (termed outcrossing i.e., sexual reproduction). The rate of outcrossing in a population can be used as an index of how much selection is favoring sexual reproduction (outcrossing) over asexual...

Which pattern of survivorship is most likely for an organism such as the penguin, which produces only a single offspring at a time,
7. Which pattern of survivorship is most likely for an organism such as the penguin, which produces only a single offspring at a time, provides a lot of parental care and has a relatively long lifespan? Most offspring survive for most of their potential life span and then die at approximately the same time. The probability of death due to natural causes is high throughout the life span. Survivorship is low early in life and then levels off. Young individuals have a...

A proponent of the efficient markets hypothesis would be most likely to agree with which of the following statements? When a security has recently been experiencing high rates of return, it's likely to experience less-than-average rates of return in the future. After adjusting for things like transactions and information costs, stocks sell for a good approximation of their fundamental value. Over the long run, financial investment in small firms has been more profitable than in large firms. All of the...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
