When one X chromosome in the somatic cells of mammals in inactivated during embryonic development, meaning that its genes are not expressed is known as what? What forms as the inactivated chromosome? </p><p>3. Describe Maternal effect</p><p>4. A particular allele can have different effects if it is inherited from a male rather than a female. This phenomenon is known as ______. </p><p>5. How do Species and Population differ? a.i. Species: </p><p> a.ii. Population: </p><p>6. Which is the smallest unit that can evolve; species or population? </p><p>The people involved and their Proposals </p><p>_____ Developed the study of fossils, opposed evolution, Advocated catastrophism</p><p>_____Founded taxonomy, binomial nomenclature</p><p>______Developed a theory similar to Darwin’s accept 20 years after. </p><p>_____1st to state evolutionary change but had the wrong mechanism. Hypothesized that species evolve through use and disuse and through the inheritance of acquired traits. </p><p>_____First scientist to carry out a thorough study of the living world, developed an early classification system, established the modern concept of a species </p><p>_____This person’s view on life was descent with modification </p><p>_____Advocated Uniformitarianism (mechanism of change are constant over time) </p><p>A.
