When sperm meets egg this is called ____________.
What is fertilization?
200
The type of cell division that produces gametes.
What is meiosis?
200
Genes located on homologous chromosomes may have alternate forms that control different forms of a trait. These alternate forms of a gene are called ___________.
What are alleles?
200
The ________________ produced by each parent are shown along the sides of a Punnett square.
What is alleles, genes or gametes?
300
This can result in offspring having too many or too few chromosomes.
What is non-disjunction?
300
The genes that an organism has for a trait (note - even the genes that don't show).
What is genotype.
300
The cell produced when a male gamete fuses with a female gamete.
What is a zygote?
300
A dog's phenotype can be determined by _______________.
What is looking at the dog?
300
Having both a dominant and recessive allele for a trait.
What is heterozygous?
400
A punnett square cross involving two different traits.
What is a dihybrid cross?
400
Cells containing two alleles for each trait are described as ________________ (hint - they would also have to have two of those chromosomes).
What is diploid?
400
The exchange of genetic material between homologous chromosomes.
What is crossing over.
400
In mink, brown fur color is dominant to silver-blue fur color. If a homozygous brown mink is mated with a silver-blue mink and 8 offspring are produced, how many would be expected to be silver-blue?
What is zero?
400
Having the same two alleles for a trait.
What is homozygous?
500
In chickens, rose comb (R) is dominant to single comb (r). A homozygous rose-combed rooster is mated with a single combed hen. All of the chicks in the F1 generation were kept together and only allowed to mate within their group. What is the expected phenotype of the F2 chicks?
What is 75% rose comb, 25% single comb?

What is homozygous recessive.

The Law of Independent Assortment states that the inheritance of alleles for one trait is not affected by the inheritance of alleles for a different trait if the genes for those traits are on ____________________.
What is separate chromosomes?
