Heredity
Heredity is the passing of traits from parents to offspring.
What are genes?
Genes are segments of DNA that carry the instructions for making proteins and determining traits.
What is dominant inheritance?
Dominant inheritance occurs when a trait is expressed if at least one dominant allele is present.
How are traits inherited?
Traits are inherited through the alleles passed from parents to offspring.
Who is Gregor Mendel?
Gregor Mendel is known as the father of genetics for his work on the inheritance of traits in pea plants.
What is a trait?
A trait is a characteristic or feature of an organism, such as eye color or height.
What is DNA?
DNA (deoxyribonucleic acid) is the molecule that carries genetic information in living organisms.
What is recessive inheritance?
Recessive inheritance occurs when a trait is expressed only when two recessive alleles are present.
What is selective breeding?
Selective breeding is the process of choosing specific plants or animals to breed to produce desired traits.
What are Mendel's laws?
Mendel's laws include the law of segregation and the law of independent assortment, which describe how traits are inherited.
What is a phenotype?
A phenotype is the physical expression of a trait in an organism.
What is the role of chromosomes?
Chromosomes are structures that hold DNA and contain many genes; they ensure proper distribution of genetic material during cell division.
What is co-dominance?
Co-dominance is when both alleles in a gene pair are fully expressed in the phenotype, resulting in a blend of traits.
What is cloning?
Cloning is the process of creating a genetically identical copy of an organism.
What is an allele?
An allele is a variant form of a gene that can cause different traits.
What is a genotype?
A genotype is the genetic makeup of an organism, consisting of alleles inherited from its parents.
What is a mutation?
A mutation is a change in the DNA sequence that can lead to changes in traits or functions.
What is incomplete dominance?
Incomplete dominance is when the phenotype is a mix of the two parents' traits, neither allele is completely dominant.
What are genetically modified organisms?
Genetically modified organisms (GMOs) are organisms whose genetic material has been altered using genetic engineering techniques. What are genetically modified organisms?
What is a monohybrid cross?
A monohybrid cross is a genetic cross that involves one trait, examining the inheritance of a single pair of alleles.
What is a Punnett square?
A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.
What is genetic engineering?
Genetic engineering is the manipulation of an organism's DNA to alter its characteristics or traits.
What is a pedigree chart?
A pedigree chart is a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism from one generation to the next.
What is gene therapy?
Gene therapy is a technique that modifies genes to treat or prevent disease.
What is a dihybrid cross?
A dihybrid cross is a genetic cross that examines the inheritance of two different traits simultaneously.
