ANSC 1011 (Animal Science) FINAL
EXAM STUDY QUESTIONS AND
ANSWERS FOR CROSSLAND.
The transmission of genes from parent to offspring at the time of
conception.
inheritance
The genetic makeup of an organism.
genotype
Observable characteristics that result from the interaction of genotype and
environment.
phenotype
The basis of an animal's worth is the _______ of genotype into traits of
economic importance.
expression
A complex molecule composed of nucleotides joined together with
phosphate sugars.
DNA
Contains large molecules of DNA. Composed of segments called genes.
chromosomes
Small sections of DNA that code for a specific purpose. Direct the synthesis
of proteins or perform regulatory functions.
gene
,Observable characteristic; What makes you who you are.
trait
