Heredity - Passing Traits to Offsprings

What is heredity?

• Passing of traits from parents to offspring through genetic information.

• Inheritance of acquired characteristics.

• Passing of traits from parents to unrelated individuals.

• Passing of traits from offspring to parents.

Who is known as the father of genetics?

• Charles Darwin

• Isaac Newton

• Albert Einstein

• Gregor Mendel

What are genes?

• Genes are proteins that carry out specific functions in the body.

• Genes are small molecules that make up the building blocks of DNA.

• Genes are only found in humans and not in other organisms.

• Segments of DNA that contain instructions for building and maintaining an organism.

What is the difference between genotype and phenotype?

• Genotype and phenotype are the same thing.

• Genotype refers to the traits that are influenced by the environment, while phenotype refers to the genetic makeup.

• Genotype refers to the genetic makeup of an organism, while phenotype refers to the observable characteristics or traits of an organism that are influenced by its genotype.

• Genotype refers to the physical appearance of an organism, while phenotype refers to the genetic makeup.

What is a dominant trait?

• A dominant trait is a genetic trait that is expressed or observed when an individual has only one copy of the gene associated with the trait.

• A dominant trait is a genetic trait that is not influenced by the environment.

• A dominant trait is a genetic trait that is only observed in males.

• A dominant trait is a genetic trait that is expressed or observed when an individual has two copies of the gene associated with the trait.

What is a recessive trait?

• A recessive trait is a genetic trait that is only expressed when an individual has one copy of the recessive allele.

• A recessive trait is a genetic trait that is only expressed when an individual has two copies of the recessive allele.

• A recessive trait is a genetic trait that is always expressed in an individual.

• A recessive trait is a genetic trait that is only expressed in males.

What is the Punnett square used for?

• To study the effects of mutations on gene expression.

• To analyze the structure of DNA.

• To predict the possible outcomes of a genetic cross.

• To determine the gender of an individual.

What is the difference between homozygous and heterozygous?

• Homozygous refers to having two different genes, while heterozygous refers to having two identical genes.

• Homozygous refers to having two alleles for a particular gene, while heterozygous refers to having only one allele for a particular gene.

• Homozygous refers to having two different alleles for a particular gene, while heterozygous refers to having two identical alleles for a particular gene.

• Homozygous refers to having two identical alleles for a particular gene, while heterozygous refers to having two different alleles for a particular gene.

What is a genetic mutation?

• A genetic mutation is a change in the RNA sequence.

• A genetic mutation is a change in the protein sequence.

• A genetic mutation is a change in the cell structure.

• A genetic mutation is a change in the DNA sequence.

What is genetic inheritance?

• Genetic inheritance is the result of environmental factors affecting an organism's traits

• Passing of traits from parents to offspring through genes

• Genetic inheritance is the passing of traits from offspring to parents

• Genetic inheritance is the result of random mutations in an organism's DNA
