BIOL3200 QUIZ 4 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
Gene
Segregating heritable determinant of phenotype
Fundamental physical functional unit of heredity
Segment of DNA made of transcribed region and regulatory sequences
Human Genome Nomenclature Organization definition of a gene
DNA segment contributing to phenotype
Locus
Position on a chromosome
The position on chromosome of a gene or other chromosome marker
Can also mean DNA at the position
Use of locus sometimes restricted to mean regions of DNA expressed
FISHing
Fluorescence in situ hybridization
Allele
Gene variant
Different alleles make differnet phenotypes
Diploids have two copies of a gene
Hetero has 2 dif alleles
Homo has 2 same allele
, Genotype definition
Genetic makeup of an organism
Description of alleles of an individual
Allele frequency formula
(2*Homozygotes + Heterozygotes)/total
Genotype frequency formula
(# individuals with each genotype)/(total sample population)
Phenotype
Physical/behavrioral trait of individual
Interaction of genes and environment
Genetic component only is heritable
richard dawkins' phenotyp argument
Phenotype can extend outside yourself, can be how you modified environment
(scorpion burrow, caddisfly shell)
Gamete
Germline cell that can unite with opposite sex cell in sex reproduction
Made in meiosis
Has half chromosomes of parent
Zygote
Earliest developmental stage of embryo
Made of fusion of 2 gametes
has two haplotypes
Dominant and Recessive
