Question 1
The exact same genotype is seen only in
◦ identical twins.
◦ members of a family.
◦ non-identical twins.
◦ members of a population.
◦ brothers and sisters of different ages.
Question 2
The fossil record is biased because
◦ most species we have fossils for lived on land or in shallow seas that became part of the continents.
◦ have very few fossils from sediments beneath the ocean even though it covers three fourths of the earth.
◦ most fossils come from the Northern Hemisphere because most geologists have lived and worked there.
◦ both most species we have fossils for lived on land or in shallow seas that became part of the continents and most fossils come from the Northern Hemisphere because most geologists have lived and worked there..
