WGU C653 HEREDITY AND GENETICS
COMPLETE EXAMINATION TEST
QUESTIONS WITH VERIFIED SOLUTIONS
●● heredity
Answer: the passing of traits from one generation to the next
●● trait
Answer: a specific characteristic that varies from one individual to
another
●● gene
Answer: sequence of DNA that codes for a protein and thus determines a
trait
●● genome
Answer: the entire "library" of genetic instructions in DNA that an
organism inherits
●● Gregor Mendel
Answer: father of genetics
, ●● allele
Answer: alternative form of a gene (one member of a pair) located at a
specific position on a specific chromosome (a letter)
●● dominant allele
Answer: an allele that produces the same phenotype whether its paired
allele is identical or different (capital letter)
●● recessive allele
Answer: an allele that produces its characteristic phenotype only when
its paired allele is identical (lowercase letter)
●● genotype
Answer: the combination of alleles located on homologous
chromosomes that determines a specific characteristic or trait (the allelic
combination such as Bb)
●● phenotype
Answer: the observable physical or biochemical characteristics of an
organism, as determined by the genotype (the expressed trait such as
brown eyes)
●● homozygous
