When alleles for different characteristics are on separate chromosomes, they are distributed to gametes independently. This observation is summarized by the law of
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
In guinea pigs, black fur is dominant. A black guinea pig is crossed with a white guinea pig. If the litter contains a white offspring, the genotype of the black-haired parent is probably
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
In a monohybrid cross between two heterozygous parents, one would expect the offspring to be
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
If two parents with dominant phenotypes produce an offspring with a recessive phenotype, then probably
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
Incomplete dominance is shown when

both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
An organism that is homozygous for flower color could have the genotype Qq.
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
To determine the genotype of an individual that shows the dominant phenotype, you would cross the individual with one that is
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
homozygous recessive
1 PP : 2 Pp : 1 pp
heterozygous
In a dihybrid cross between an individual with the genotype RRYY and an individual with the genotype rryy, all of the offspring will have the genotype
RrYy
independent assortment
both parents are heterozygous
False
a black guinea pig is crossed with a white quinea pig to produce a grey guinea pig.
