An allele that cannot be expressed in the presence of a recessive allele.

Answer

An allele that is always expressed in the phenotype, regardless of other alleles.

Answer

An allele that only appears in homozygous conditions.

Question 14

No visible phenotype

Answer

A blend of both phenotypes

Answer

The recessive phenotype

Question 15

Accepted Answer

Alleles for different traits are distributed to gametes independently of one another.

Answer

Dominant traits overshadow all others

Answer

Only one trait can be expressed in an organism

Answer

All traits are inherited together

Question 16

What does Mendel's law of segregation state?

Accepted Answer

Alleles segregate independently during gamete formation.

Answer

Only dominant alleles are expressed

Answer

Genes blend together in offspring

Answer

All traits are inherited equally

Question 17

What is the main conclusion of Gregor Mendel's experiments with pea plants?

Accepted Answer

Traits are inherited according to specific patterns.

Answer

Traits are inherited randomly with no patterns

Answer

Traits can only be passed if both parents express them

Answer

All traits are acquired during an organism's life

Question 18

What does it mean for an allele to be recessive?

Accepted Answer

It is only expressed in the phenotype when two copies are present.

Answer

It is always expressed in the phenotype.

Answer

It can never be inherited.

Answer

It is stronger than dominant alleles.

Question 19

What is the purpose of a test cross in genetics?

Accepted Answer

To determine the genotype of an organism with a dominant phenotype.

Answer

To cross two organisms with the same genotype.

Answer

To observe the effects of mutations on traits.

Answer

To introduce new alleles into a population.

Question 20

In Mendelian genetics, what is a homozygous genotype?

Accepted Answer

A genotype with two identical alleles for a specific trait.

Answer

A phenotype that expresses both dominant and recessive traits.

Answer

A genotype that is not influenced by environmental factors.

Answer

A genotype with two different alleles for a specific trait.

Question 21

What type of cross did Mendel use to determine the dominant and recessive traits in pea plants?

Accepted Answer

Monohybrid cross.

Answer

Test cross.

Answer

Back cross.

Answer

Dihybrid cross.

Question 22

What is the phenotype of an organism?

Accepted Answer

The observable characteristics or traits of an organism.

Answer

The genetic composition of the organism.

Answer

The process of allele segregation.

Answer

The frequency of a trait in a population.

Question 23

What is a genotype?

Accepted Answer

The genetic makeup of an organism for a specific trait.

Answer

The physical appearance of an organism.

Answer

The environment affecting an organism's traits.

Answer

Question 24

According to Mendel's law of independent assortment, how do alleles for different traits segregate during gamete formation?

Accepted Answer

Alleles for different traits segregate independently of one another.

Answer

Alleles for the same trait segregate together.

Answer

Alleles for different traits are always inherited together.

Answer

All alleles are lost during gamete formation.

Question 25

What is the principle of segregation in Mendel's laws of inheritance?
