Atrue-breeding long-eared owl mates with a true-breeding short-eared owl and all their many, many offspring were also short-eared. ear length in owls is controlled by a single gene, e. what can you conclude about the parents' genotypes? choose all correct answers.
the short-eared parent's genotype must be ee.
the long-eared parent's genotype must be ee.
the long-eared parent's genotype must be ee.
the short-eared parent's genotype must be ee.
the short-eared parent's genotype must be ee.
the long-eared parent's genotype must be ee

the answer for this question is : Ee, ee

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
