In a pedigree, a carrier for a non sex-linked gene would be represented as a(n)
normal individual.
circle.
square.
individual who has a genetic disorder.
3
A situation in which a gene has more than 2 alleles is known as
complete dominance
polygenic dominance
multiple alleles
codominance
4
A testcross produces both purple & white-flowering plants. The original purple-flowering plant
is Pp
There is not enough information.
is PP
is pp
5
Good choice of genotype for a testcross to find out the genotype that might be Ww or WW
heterozygous recessive
a Ww offspring
homozygous recessive
WW offspring
6

and
ww
all homozygous recessive
1 WW: 2 Ww :1 ww
all heterozygous recessive
all Ww offspring
