1. In white fish, light grey coloring of
the scales can mask over the allele of
dark grey scales. So when a white fish
with light grey scales has offspring with
dark grey scales, all the offspring have
light grey scales.
Which of Mendel’s Laws best explains
this?
The Rule/Law of Dominance- One trait
can mask the expression of the other.
2. Many traits such as spots on body,
length of fins, and color of skin can be
observed on catfish. It is possible to see
any combination of these traits in
individual catfish.
Which of Mendel’s Laws best explains
this?
The Law of Independent Assortment- if
genes are located on separate
chromosomes they are inherited
independently.
3. In humans, hairline shape (smooth or
widow’s peak) is coded for by a single
pair of genes. A man with
a widow’s peak has several children with
a woman who also has a widow’s peak
and some of the children have a smooth
hairline.
Which of Mendel’s Laws best explains
this?
The Law of Segregation- Only one allele/gene
can be passed down from parent to offspring.
Allowing traits that are not seen in parents to
become visible in next generation of offspring.
4. Every pea plant has 2 genes for each
of their traits. One gene they received
from the egg in the ovule/ovary, the other
gene they received from sperm in the
pollen.
Which of Mendel’s Laws best explains

organism has two factors/genes for each
trait.

Quiz Wiz 1-8 ANSWERS
1. Is Meg’s lack of popularity in
her genes or due to her
environment? Lois is homozygous
for being popular and Peter is
hybrid for being popular.
DUE TO HER ENVIRONMENT
She is either purebred or hybrid
popular. Phenotype is due to
genotype + environment
