30 Questions
What phenomenon can result in offspring that produce a higher yield than their true-breeding parents?
Epistasis
How is epistasis different from complete dominance?
Epistasis involves interactions between alleles of different genes, while complete dominance involves interactions between alleles of the same gene.
In genetics, what is the term used for the presence of more than two alleles of a gene in a population?
Multiple alleles
What type of trait is expressed only in one sex, regardless of whether it is X-linked or not?
Sex-limited trait
Which genetic phenomenon involves one gene interfering with the expression of another gene?
Epistasis
What does it mean when a heterozygote can express a phenotype that is more extreme than either parent?
Epistasis
What is the main focus of Population Genetics?
Studying gene frequencies and allele changes
Which field of genetics is primarily concerned with the function of enzymes in metabolic pathways?
Biochemical Genetics
How does Evolutionary Genetics contribute to genetic studies?
By exploring genetic variation for speciation
Which application area of genetics involves the improvement of crops through selective breeding?
Plant, Animal, and Microbial Improvement
In the context of genetics, what is the primary purpose of genetic counseling?
Identifying diseases with genetic bases for treatment
How does Behavioral Genetics differ from other branches of genetics mentioned?
By studying how genes influence behavior
Who is often referred to as the 'Father of Genetics'?
Gregor Mendel
Which scientist proposed the theory of Pangenesis regarding the formation of semen?
Aristotle
Who put forward the Theory of Inheritance of Acquired Characteristics as a fundamental mechanism of evolutionary change?
Jean Baptiste de Lamarck
Which group of scientists duplicated Mendel's experiments on various plants like garden peas, maize, and primroses?
Gregor Mendel, Erick Von Tschermak and Hugo de Vries
Who demonstrated that Mendel's principles also applied to animals in 1902?
William Bateson, Saunders and Cuenot
What is the core focus of Genetics as a branch of biology?
Understanding molecular and physical bases of biological diversity
Who confirmed the Chromosome Theory of Inheritance by discovering the sex chromosomes and demonstrating the association between specific genes and specific chromosomes?
Thomas Hunt Morgan
What did Sutton and Boveri suggest in 1902 regarding the association of Mendelian factors with chromosomes?
There are resemblances in behavior between Mendelian factors and chromosomes
Who identified DNA as the hereditary material in 1944?
Maclyn McCarty
What does Cytogenetics study?
The chromosomes
Which branch of genetics focuses on how genes control the growth and development of an organism throughout its life-cycle?
Developmental Genetics
What does Quantitative Genetics study?
Traits controlled by many genes and affected by the environment
What term is used to refer to phenotypic traits that vary in degree due to the influence of two or more genes and the environment?
Multiple alleles
Which type of genetic trait displays contrasting phenotypes based on the sex of the individual?
X-linked traits
In what way do autosomal genes contribute to the phenotypic expression of males and females?
By influencing gene expression based on hormonal constitution
What characteristic distinguishes multiple alleles from other types of genetic traits?
They vary in degree due to two or more genes and the environment
Which type of trait is typically measured on a continuous scale or spectrum?
Polygenic traits
What aspect influences the phenotypic expression of an organism besides genetic factors?
Environmental conditions
