1.
What is the role of a Punnett square in genetics?
a)
It predicts the possible genotypes and phenotypes of offspring.
b)
It determines the physical traits of an individual.
c)
It shows the structure of DNA molecules.
d)
It identifies the number of chromosomes in a cell.
2.
What is the difference between a genotype and a phenotype?
a)
Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical expression of traits.
b)
Genotype is the observable characteristics, while phenotype is the genetic sequence.
c)
Genotype is the combination of alleles in an individual, while phenotype is the potential for those alleles to produce traits.
d)
Genotype is the trait that is visible, while phenotype is the underlying genetic information.
3.
What is the term for the physical expression of a gene in an organism?
a)
genotype
b)
phenotype
c)
chromosome
d)
allele
4.
What is the term for two alleles that control the phenotype of a trait?
a)
genotype
b)
phenotype
c)
chromosome
d)
polygenic inheritance
5.
What is the term for a phenotype that is a blend of the parents’ phenotypes?
a)
incomplete dominance
b)
codominance
c)
polygenic inheritance
d)
genotype
6.
What is polygenic inheritance?
a)
A type of inheritance where one trait is controlled by one gene.
b)
An inheritance pattern where multiple genes influence a trait.
c)
A situation where only dominant genes are expressed.
d)
An inheritance model that predicts phenotypes based on a single gene.
7.
What is the term for a diagram that shows the genetic relationships between family members?
a)
pedigree
b)
genotype
c)
Punnett square
d)
chromosome
8.
What does it mean for an organism to be homozygous for a trait?
a)
The two genes in a hybrid are dominant.
b)
The two alleles in a genotype are the same.
c)
The two traits in a phenotype are different.
d)
The organism has one dominant and one recessive allele.
9.
Which term describes the genetic makeup of an organism?
a)
genotype
b)
phenotype
c)
chromosome
d)
allele
10.
What is codominance in genetics?
a)
A genetic scenario where one allele is completely dominant over another.
b)
A genetic scenario where both alleles contribute equally and visibly to the phenotype.
c)
A situation in which only one allele's traits are expressed.
d)
A condition where traits blend together to form an intermediate phenotype.
11.
What is the term for a trait that is determined by multiple genes interacting with each other?
a)
polygenic inheritance
b)
homozygous trait
c)
dominant trait
d)
codominance
12.
What is the term for the genetic information that is passed from parents to their offspring?
a)
DNA
b)
Gene
c)
Chromosome
d)
