Describe an ideal thesis statement.
An ideal thesis statement is a clear, concise assertion of the main point or argument of an essay. A thesis statement is often expressed in one sentence towards the end of the opening paragraph of an essay, supported throughout the essay, and reiterated before the essay's close.
Define polyspermy and explain why it is lethal to the developing human zygote. Use the term “chromosomes” in your explanation.
Polyspermy is the fertilization of a single egg by multiple sperm. It is lethal to the developing human zygote because it results in too much genetic information for the developing zygote: too much paternal DNA, more than a full set of chromosomes.
