Genetics: Mendelian Inheritance

What is Mendelian inheritance?

• Mendelian inheritance involves the blending of genetic material from parents

• Mendelian inheritance only occurs in plants, not in animals

• Mendelian inheritance is the passing of genetic information from one generation to the next through discrete units called genes.

• Mendelian inheritance refers to the transmission of acquired traits from parents to offspring

Who is known as the father of genetics?

• Gregor Mendel

• Isaac Newton

• Albert Einstein

• Marie Curie

What are the two types of alleles in Mendelian genetics?

• co-dominant and incomplete

• dominant and recessive

• homozygous and heterozygous

• parental and offspring

Explain the difference between homozygous and heterozygous genotypes.

• Homozygous genotypes are only found in plants, while heterozygous genotypes are only found in animals.

• Homozygous genotypes always result in genetic disorders, while heterozygous genotypes do not.

• Homozygous genotypes have more chromosomes than heterozygous genotypes.

• The main difference between homozygous and heterozygous genotypes is the presence of identical alleles in homozygous and different alleles in heterozygous genotypes.

What is a Punnett square used for in Mendelian genetics?

• Identifying the location of a gene on a chromosome

• Calculating the probability of a genetic disorder

• Predicting possible genotypes of offspring in a genetic cross.

• Determining the dominant traits in an individual

What is the difference between genotype and phenotype?

• Genotype refers to physical characteristics, while phenotype refers to genetic makeup

• Genotype and phenotype are the same thing

• Genotype is only relevant in plants, while phenotype is only relevant in animals

• Genotype is the genetic makeup, while phenotype is the physical characteristics.

How does Mendel's law of segregation apply to genetic inheritance?

• Mendel's law of segregation states that genetic traits are always dominant

• Mendel's law of segregation only applies to plants, not animals

• Mendel's law of segregation does not impact genetic variation

• Mendel's law of segregation applies to genetic inheritance by explaining how alleles segregate and are passed down from parents to offspring, contributing to genetic variation.

What is a monohybrid cross?

• A monohybrid cross involves crossing two individuals with completely different genetic backgrounds.

• A monohybrid cross is a genetic cross between two individuals that are heterozygous for one particular gene of interest.

• A monohybrid cross is a type of genetic cross that only involves one parent.

• A monohybrid cross is a genetic cross between two individuals that are homozygous for all genes.

What is the difference between dominant and recessive alleles?

• Recessive alleles are more common in the population

• Recessive alleles are always expressed in the phenotype

• Dominant alleles are always inherited from the mother

• Dominant alleles are expressed over recessive alleles in an individual's phenotype.

Explain the concept of incomplete dominance in genetics.

• Incomplete dominance is when neither of two alleles is dominant, resulting in a blending of traits.

• Incomplete dominance is when one allele completely masks the expression of the other allele.

• Incomplete dominance is when both alleles are expressed equally, resulting in a mix of traits.

• Incomplete dominance is when one allele is always dominant over the other allele.
