possible traits of offspring.
What is a Punnett Square
A term used to describe a genotype
that includes one dominant allele and
.
one recessive allele (for example: Bb)
What is heterozygous?
A mink with brown fur (BB) is
mated with a silver mink (bb).
100% of the offspring would have
this genotype.
What is heterozygous?

mouse. All their offspring are brown.
The genotype of the mouse is most
likely this.
What is homozygous recessive?
It is the phenotypic ratio for a cross
between 2 heterozygous parents.
dominant: recessive

can be inherited is called this
What is a trait?
A recessive allele may be masked
by one of these alleles..
What is a dominant allele?
A Punnett square that only
predicts the results of one trait is
called this
What is a monohybrid cross?
The event responsible for increasing
genetic variety during meiosis is
called this
What is crossing over?
It is the term that refers to the
physical appearance of a trait.
What is a phenotype?
It is the term used to describe the
genetic make up or genes of an
organism
What is genotype?
