Questions and Answers

Match the genetic concepts with their definitions:

Genotype = Letter combination used to represent traits of an organism Phenotype = What is physically seen in an organism Allele = Different forms of a gene Heterozygote = Genotype that has different alleles

Match the terms with their descriptions:

Mendel = Father of genetics GMO = Genetically Modified Organism Transgenic = Combining DNA from different cells/organisms Acquired Traits = Characteristics gained during a lifetime

Match the laws of genetics with their explanations:

Law of Segregation = Two alleles for each trait will separate during meiosis Law of Independent Assortment = Random distribution of alleles occurs during gamete formation Probability = The likelihood that something will happen Recessive Allele = Allele that only shows when it's by itself

Match the types of alleles with their characteristics:

<p>Dominant Allele = Allele that when present always shows up Recessive Allele = Allele that only shows when it's by itself Homozygous = Genotype that has the same alleles Heterozygous = Genotype that has different alleles</p> Signup and view all the answers

Recessive allele

A form of a gene that is only expressed when two copies are present.

Heterozygote

A genotype with two different alleles for a particular gene.

Homozygote

A genotype with two identical alleles for a particular gene.

Dominant allele

A form of a gene that is expressed even when only one copy is present.

Study Notes

Genetic Engineering

  • Genetic engineering involves changing a DNA sequence.

Punnett Square

  • A chart used to predict probabilities in offspring.

Recessive Allele

  • An allele that only shows when it's by itself.

Heterozygote

  • A genotype with different alleles.

Transgenic

  • Combining DNA from different cells or organisms.

Probability

  • The likelihood that something will happen.

Homozygote

  • A genotype with the same alleles.

Mendel

  • Considered the father of genetics.

GMO

  • Genetically Modified Organism.

Acquired Traits

  • Characteristics gained during a lifetime.

Law of Independent Assortment

  • Alleles are randomly distributed during a lifetime.

Allele

  • Different forms of a gene.

Genetic Mutation
