The gamete that contains genes contributed only by the mother is
What is an egg cell?
100
When homologous chromatids exchange small sections with each other.
What is crossing over.
100
The result of crossing over.
What is genetic recombination?

During his studies on the genetics of peas, Mendel discovered three laws of inheritance
What is independent assortment, segregation, and recombination?
200
The offspring from the P generation are called the _____ or ___.
first filial generation or F1 generation
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
For a series of breeding experiments, a linkage group composed of genes A, B, C, and D was found to show the following gene combinations. (All recombinations are expressed per 100 fertilized eggs). Construct a chromosome map. A B C D A – 12 15 4 B 12 – 3 8 C 15 3 – 11 D 4 8 11 –
What is A,D,B,C.
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.
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 genetic cross between individuals with different alleles for two gene loci of interest.
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
The crossover frequency between genes E and F is 6%, between E and G is 10% and between F and G is 4%. Construct a map of these genes.
What is E,F,G?
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?
500
A white mouse whose parents are both white produces only brown offspring when mated with a brown mouse. The white mouse is most probably ____________.
What is homozygous recessive.
500
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?
500
A blue-eyed man with normal color vision mates with a women who is heterozygous for brown eyes and has normal vision; however, the women's father was colorblind. Blue eye color is autosomal recessive, and colorblindness is an X-linked recessive trait. What is the phenotypic ratio of male offspring?
What is 1:1:1:1; brown, normal: brown, albino: blue, normal: blue, albino?

In the statement, "In meiosis, the way in which a chromosome pair separates does not affect the way other pairs separate," is another way of expressing Mendel's law of _______________________.
