CSET Genetics Exam With Questions And 100%
Correct Solutions
Homozygous - ANSWER term used to describe an individual organism that possesses
two identical alleles for any particular trait BB
when a strain of fruit flies homozygous for light body color is crossed with a strain of
fruit flies homozygous for dark body color, all of the offspring have light colored bodies.
This illustrates the principle of? - ANSWER dominance B
dominance - ANSWER An organism with a dominant allele for a particular form of a trait
will always display that form of the trait. ex. Bb ---The big B would be dominant B
segregation - ANSWER (genetics) the separation of paired alleles during meiosis so that
members of each pair of alleles appear in different gametes
incomplete dominance - EXERCISE produces a blended phenotype; neither allele is
completely dominant over the other
independent assortment - EXERCISE describes the property of genes for different
characteristics to segregate independently of each other during the formation of
gametes and explains why many genetic combinations are possible in plants, animals
and other organisms
heterozygous - EXERCISE the term to describe an organism that has two different
alleles for a specific trait Bb
recessive - ANSWER The inherited characteristic often masked by the dominant
characteristic and not seen in an organism. bb
