Mendel's discovery that short plans would reappear in F2 generation supported his theory that
recessive allelesonly show when dominant allele not present
alleles are separated when organisms produce gametes
all of the above
each parent contributes one allele for a trait
12

osmosis
DNA replication
mitosis
crossing over
13
Which of the following is a haploid cell?
a cell at the end of meiosis
a cell at the beginning of mitosis
a cell at the beginning of meiosis
a cell at the end of mitosis
14

75%
25%
50%
0%
15
Wilson's disease is an inherited trait; Neither parent has the trait. How can a child have it?
Wilsons is dominant allele
Wilsons occurred because of mutation
Wilson's cannot be inherited
the allele for Wilsons is recessive
