Monosomy B. Nondisjunction C. Zygote D. Trisomy Question: Select the correct answer for each blank: The process of copying segment of DNA within the nucleus into a strand of mRNA is known as translation/transcription. The process of whereby stands of mRNA are used to synthesize a strand of amino acids that will eventually form a protein, is known as transcription/translation. Question: Choose the best term for each blank: Homozygous/homologous refers to two chromosomes that have the same types of genes on them while homozygous/homologous refers to an individual who has two of the same alleles for one gene. Question: Choose the best phrase for each blank: The principle of segregation/independent assortment refers to the two copies (alleles) of a particular gene which will be separated when sex cells are created.

Question: What was the most common reproductive state for Dogon women aged 20-34? Question: What was the most common number of menstrual cycles for Dogon women in Dr. Strassman’s study over her two year study period? Question: High breast cancer incidence in contraceptive, westernized population is likely the result of a mismatch to which of the following lifestyle factors? (I.e. what are women in these populations probably not well-adapted to?) Question: True or False: Women in modern societies have fewer menstrual cycles than women in non-contraceptive societies?

(choose all that apply) Question: Birth in australopithecines would have been more difficult than in chimpanzees because australopithecines have larger brains and therefore, larger head sizes at birth. Question: Primates are characterized by altricial/precocial patterns of growth compared with other mammals which means that they are relatively less/more developed. Question: Humans are characterized by altricial/precocial patterns of growth compared with other primates which means that they are relatively less/more developed.
