BIOL 1107 Study Guide - Midterm Guide: Meiosis, Oviparity, Sex Steroid
Document Summary
When researchers identify the genetic, developmental, hormonal, or neural mechanisms responsible for a phenotype, they are working at the proximate level: fertilization of of an egg by sperm to form this diploid cell. The eggs produced by parthenogenesis develop here and are released when the female molts her exoskeleton female offspring develop from unfertilized eggs. These offspring are genetically identical to the mother. Produce an antibiotic compound which may prevent urinary tract infections in males and citric acid which is a nutrient compound for the sperm: hermaphroditism. Divide by meiosis to form four haploid products undergo meiosis i and produce two secondary spermatocytes: the formation of sperm. Polar body: proximate causation addresses why a trait occurs, in terms of its effect on fitness the focus is on the evolutionary history of traits. Produce an antibiotic compound which may prevent urinary tract infections in males and citric acid which is a nutrient compound for the sperm.
