Father of Genetics
What is the passing of traits from parents to offspring?
Heredity
Genetics
Traits
Mendelian
How a trait in physically expressed in an organism is a
phenotype
genotype
gene
dominant
What type of inheritance do two alleles have if their traits are expressed in equal amounts at the same time?
In chickens, feather color is incomplete dominant. If a black chicken BB is mated with one that is black and white (BW) what are the chances of having a chicken that is gray?
A kitten is black. Both parents are white. What genotypes are the parents?
one is homozygous recessive and the other is homozygous dominant
both must be heterozygous
both must be homozygous recessive
sex-linked
dominant
Butterflies have a gene for wing color that has incomplete dominance. BB is blue and YY is yellow. Their offspring will have what phenotype?
BY
By
Green
Blue
A chart that displays family relationships indicating traits or disorders
Punnett square
Pedigree
Karyotype chart
This disorder is called "Cry of the cat", comparing the normal chromosome on the left to the mutated one on the right, what type of mutation is this?
Inversion
Translocation
Deletion
Duplication
Why do sex-linked disorders affect men more than women?
males only have 1 X chromosome
males do not have an X chromosome
girls always have 2 defective X chromosomes
males only have Y chromosomes
A carrier is
A person who is heterozygous for a recessive disorder
A person who is homozygous dominant for a disorder
A person who is homozygous recessive for a disorder
If a dominant allele is found on at least on of an organism's homologous chromosomes, what can be said about the physical expression of that trait?
It will have that trait because only one dominant allele is needed to express that trait
It will not have that trait because both dominant allele is needed to express that trait.
It will not have that trait because only one recessive allele is needed to express that trait

2/4
1/4
What pattern of non-Mendelian inheritance is shown by ABO blood group?
Codominance
Incomplete Dominance
Multiple Alleles

AA or ii
Only AB
AB, AA, Ai, Bi, or ii
AA, BB, Bi, or AB
