What does Mendel's Law of Dominance state?

Alleles can be dominant or recessive.

Traits are inherited independently.

Individuals possess only one allele.

Inheritance is a blending of traits.

According to Mendel's Law of Segregation, how are alleles passed to offspring?

Randomly pass on only one allele.

Two traits are inherited independently and do not influence one another.

Traits are blended from both parents.

Only dominant traits are inherited.

All traits are inherited together.

Why are blood sugar levels high in individuals with Type I Diabetes?

Glucose cannot be taken up by cells

The liver produces too much insulin

The pancreas produces excess glucose

The kidneys excrete too much sugar

Which genes are mentioned as being involved in Type I diabetes?

Hemoglobin genes on chromosome 16

Dystrophin genes on chromosome 21

What influences the likelihood of inheriting diabetes?

Which genes are inherited and environment

What does Mendel's Law of Segregation state about alleles during meiosis?

Alleles separate into gametes and recombine during fertilization.

Alleles are permanently combined during meiosis.

Alleles do not change during meiosis.

Alleles are destroyed during meiosis.

According to Mendel's experiments, how is the distribution of alleles to offspring determined?

It is predetermined by the parent.

It is based on environmental factors.

It is influenced by the offspring's needs.

What does the Law of Dominance state about the expression of traits?

One dominant trait is expressed over the other

Both traits are expressed equally

The recessive trait is always expressed

How can a recessive trait be expressed according to the Law of Dominance?

By inheriting two recessive alleles

By inheriting one dominant and one recessive allele

By inheriting two dominant alleles

By inheriting one allele of any type

What does the principle of independent assortment state about the inheritance of traits?

Different traits are on different chromosomes and separate into gametes independently.

Traits are inherited together as a group.

All traits are inherited from one parent.

The inheritance of one trait affects the inheritance of another.

How does the inheritance of one trait affect another according to the principle of independent assortment?

It does not affect the inheritance of another trait.

It directly influences the inheritance of another trait.

It causes all traits to be inherited together.

It ensures traits are inherited from the same parent.

What is the primary purpose of pedigree analysis in genetics?

To analyze existing mating results

In pedigree analysis, what is mapped on the family tree?

Distribution of phenotypic traits

In which situation might the inheritance of traits by a single gene deviate from simple Mendelian patterns?

When a gene has more than two alleles

When alleles are completely dominant

When there is no environmental influence

What is a characteristic of non-Mendelian inheritance?

The environment can influence phenotypic expression

Alleles are always completely dominant or recessive

Linked genes do not affect inheritance

A gene always has a single allele

What is the result of crossing a true breeding red flower parent with a true breeding white flower parent in snapdragons?

A mix of red and white f1 heterozygotes

Two dominant alleles affect the phenotype in separate, distinguishable ways.

One dominant allele affects the phenotype.

Alleles do not affect the phenotype.

Recessive alleles affect the phenotype in separate ways.

How many alleles determine the ABO blood groups in humans?

Three alleles: I A , I B , and i

Four alleles: I A , I B , i, and I O

What does it mean if a gene is pleiotropic?

It affects more than one phenotypic trait.

It affects only one phenotypic trait.

It does not affect any phenotypic trait.

It affects only genetic traits.

What are quantitative traits?

Traits that vary in a population along a continuum

Traits that are always dominant

Traits that do not vary in a population

Traits that are determined by a single gene
