What |is |evolution? |- |CORRECT |ANSWER✔✔-Changes |in |organisms |over |time
,Genes |are |composed |of |DNA. |What |does |DNA |do? |- |CORRECT |ANSWER✔✔-Specify |(encode) |
proteins
Genes |can |have |two |or |more |forms |called |__________. |- |CORRECT |ANSWER✔✔-alleles
What |is |genotype? |- |CORRECT |ANSWER✔✔-Genetic |makeup |(represented |by |letters, |one |for |
each |allele)

(proportion) |over |time
If |there |is |a |population |of |1,000 |frogs |and |360 |are |AA, |480 |are |Aa, |and |160 |are |aa, |what |are |
the |frequencies |of |a |and |A? |- |CORRECT |ANSWER✔✔-a |= |800/2,000 |= |0.4 |or |40%
A |= |1,200/2,000 |= |0.6 |or |60%

sequence
What |is |recombination? |- |CORRECT |ANSWER✔✔-Rearranging |of |existing |alleles
What |causes |mutations? |- |CORRECT |ANSWER✔✔-Errors |during |cell |division |or |damage |to |DNA
How |often |do |mutations |occur? |- |CORRECT |ANSWER✔✔-1 |every |10,000 |to |100,000 |copies |of |
a |gene
Can |you |see |evolution |occurring |in |real |time? |- |CORRECT |ANSWER✔✔-Yes, |E. |coli |and |other |
bacteria |can |replicate |in |20 |minutes, |meaning |that |within |a |day |you |can |see |changes |over |the |
course |of |many |generations
What |are |recombinations? |- |CORRECT |ANSWER✔✔-Offspring |with |combinations |of |alleles |that
|differ |from |either |of |their |parents
