Monohybrid Inheritance

Which represent a DOMINANT allele?

• D

• e

• k

• gg

Answer explanation

The correct choice for a DOMINANT allele is 'D' as dominant alleles are represented by uppercase letters in genetics.

Which represent a RECESSIVE allele?

• M

• d

• MM

• G

Answer explanation

The correct choice for a RECESSIVE allele is 'd' as it needs to be inherited from both parents to be expressed in the offspring.

Which allele combination would result in the RECESSIVE phenotype?

• DD

• Dd

• dd

• EE

Answer explanation

The allele combination 'dd' would result in the RECESSIVE phenotype because it is homozygous for the recessive allele, which is expressed in the phenotype when present.

What is the term for an individual with two DIFFERENT alleles for a particular gene?

• Homozygous

• Heterozygous

• Monohybrid

• Dihybrid

Answer explanation

An individual with two DIFFERENT alleles for a particular gene is termed as Heterozygous.

What is the term for an individual with two IDENTICAL alleles for a particular gene?

• Homozygous

• Heterozygous

• Monohybrid

• Dihybrid

Answer explanation

An individual with two IDENTICAL alleles for a particular gene is termed as Homozygous. In homozygous individuals, both alleles are the same, either dominant or recessive.

Which allele combination would result in the DOMINANT PHENOTYPE? There are more than one answers.

• TT

• Tt

• tt

• GG

Answer explanation

The allele combinations TT, Tt, and GG would result in the dominant phenotype as they contain at least one dominant allele, which masks the recessive allele.

What is the term for the GENETIC MAKEUP of an organism?

• Phenotype

• Genotype

• Allele

• Chromosome

Answer explanation

The term for the GENETIC MAKEUP of an organism is called Genotype, which refers to the specific set of genes carried by an individual.

Homozygous Dominant?

• mm

• Tt

• HH

• AB

Answer explanation

Homozygous Dominant refers to having two of the same dominant alleles, which is represented by HH in this case.

The term for gene that is expressed ONLY in the homozygous state

The term for gene that is ALWAYS expressed
