23 Questions
When is the class time and location for BIO207H5S Introductory Genetics on Tuesday?
11:00 AM - 01:00 PM, IB 110
What does the term 'cumulative' mean in the context of the final exam?
The exam will include all content covered during lectures and tutorials
What happens if a student misses a term test?
They must use the Absence Declaration tool on ACORN and contact the instructor
What was Gregor Johann Mendel known for?
Conducting experiments on pea plants and formulating hypotheses based on observations
Why was Mendel successful in his genetic experiments?
He adopted an experimental approach, interpreted results using mathematics, and was patient and thorough
What did Mendel conclude from the results of his monohybrid crosses?
Only one allele goes into each gamete when they are formed
What allowed Mendel to conduct experiments on pea plants?
Pea plants were self-fertilizing and produced many offspring, allowing artificial cross-pollination
What was the Concept or Law of Dominance proposed by Mendel?
When two different alleles are present in a genotype, only the trait encoded by one of them—the dominant allele—is observed in the F1 phenotype
What is meant by 'transmission genetics'?
The study of genetic information traveling from different parts of the body to reproductive organs
What were some advantages of using garden pea plants for Mendel's experiments?
Pea plants complete entire generation in a single growing season, produce many offspring, and are known to differ in detectably distinct characters
What is the significance of Mendel conducting monohybrid crosses?
To observe how parents that differed in a single characteristic were crossed
When did Mendel publish his work on genetic experiments?
In 1866 after conducting his experiments for 10 years
Who independently confirmed Mendel's conclusions around year 1900?
Hugo de Vries, Erich Tschermark, and Carl Correns
What does Mendel's first law, the Principle of Segregation, state?
Each individual possesses two alleles for any particular trait, and these alleles separate from each other at the time of gamete formation.
What is the molecular basis of Mendel's law of Segregation?
The independent separation of chromosomes in anaphase I of meiosis.
What does the Principle of Independent Assortment state?
Alleles at different loci separate independently of each other.
What is a Punnett square used for?
To predict the genotypic and phenotypic ratios of progeny from a genetic cross.
What is a dihybrid cross?
A genetic cross involving two individuals that differ in two characteristics.
What does a testcross help to reveal?
The genotype of the individual being tested.
What does the term 'homozygote' refer to?
An individual organism possessing two of the same alleles at a locus.
What is a backcross?
A type of genetic cross that involves an F1 genotype and either of the parental genotypes.
What does the term 'phenotype' or 'trait' refer to?
The appearance or manifestation of a characteristic.
What are homologous chromosomes?
Chromosomes that pair up during meiosis and have the same genes at the same loci.
