17 Questions
What is the primary function of histone proteins in the chromosomal structure?
To provide a basic environment for the binding of DNA
What is the characteristic of genetic material that allows it to transmit information from one generation to the next?
Capacity to carry all necessary biological information
What is the term for the process by which genetic material duplicates itself with high fidelity?
Replication
What is the primary function of non-histone chromosomal proteins?
To regulate the expression of genes through transcriptional control
What is the term for the error rate at which genetic material duplicates itself?
One or less per million (1/1 M) copies
What type of inheritance is characterized by the transmission of genes from father to son to grandson?
Y-linked inheritance
What is the term for the phenomenon where the presence of a cross-over event in one region of a chromosome affects the frequency of cross-over events in another region?
Interference
What is the term for the study of the genetic mapping of genes in haploid organisms?
Linkage mapping
What is the term for the type of linkage that occurs on sex chromosomes?
Sex linkage
What is the term for the genes that are always together in parentals and DCOs?
Linked genes
What is the term for the process by which the sex of an organism is determined?
Genetic sex determination
What is the result of a cross between two individuals with complete linkage?
100% parental types and 0% recombinant types
What is the relationship between the number of chromosomes and the number of genes in an organism?
The number of chromosomes is not related to the number of genes
What is the result of a cross between two individuals with incomplete linkage?
More than 50% parental types and less than 50% recombinant types
What is a linkage group?
A physical association of genes on a chromosome
Why are recombinants not obtained from crossing over between sister chromatids?
Because sister chromatids share the same gene
What is the purpose of a test cross in genetics?
To determine the genotype of an individual with a dominant phenotype
