Biology MBA 11 Genetics and Stuff Questions With
All Correct Answers
The science of genetics has very specific vocabulary for specific concepts.
Place the terms in the appropriate blanks to complete the sentences. correct
answer -The law of segregation states that the alleles for a particular
character segregate during gamete formation.
A dominant trait is expressed in an organism with one or two copies of the
allele.
A recessive trait is expressed only if an organism has two copies of the same
allele.
An individual organism with two of the same allele for a particular character
is homozygous.
An individual organism with two different alleles for a particular character is
heterozygous.
An individual's genotype describes which alleles are present at a specific gene
locus.
An individual's phenotype describes which trait is expressed.
Which trait is dominant and how do you know? correct answer -Wild-type
wings are dominant because wild-type parents can produce apterous
offspring, but apterous parents can't produce wild-type offspring.
What are the genotypes of each parent? correct answer -Both the male and
female are Aa.
What phenotypic ratio do you predict? correct answer -1:1
Was your prediction of a 1:1 phenotypic ratio confirmed? correct answer -
Yes, the ratio of wild-type to apterous offspring was approximately 1:1 across
all five runs.
What phenotypic ratio do you predict? (ALBINOISM) correct answer -3:1
Was your prediction of a 3:1 phenotypic ratio confirmed? (ALBINOISM)
correct answer -Yes, the ratio of unaffected to albino offspring was
approximately 3:1 across all five runs.
