Biology B final exam Review
The - correct answer -Gametes produced by each parent are shown along the sides of a punnet square
A female guinea pig homozygous dominant for black fur is mated with a male homozygous for white fur
color. In a litter of eight offspring, there would probably be - correct answer -8 black guinea pigs
Situations in which one allele for a gene is not completely dominant over another allele for that gene are
called - correct answer -Incomplete dominance
What pronciple states that during gamete formation genes for different traits seperate witjout
influencing each others inheritance? - correct answer -Principle of independent assortment
George Mendel used pea plants to study - correct answer -The inheritance of traits
A dogs phenotype can be determined by - correct answer -Looking at the dog
Organisms that have two identical alleles for a particular trait are said to be - correct answer -
Homozygous
When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited - correct answer -an
allele for tallness from the tall parent and an allele for shortness from the short parent
The principle of dominance states that - correct answer -Some alleles are dominant and others are
recessive
Mendels law of segregation states that during meiosis, the factors that control each trait seperate, and
only one factor from each pair is/are passed to the offspring. - correct answer -.
, In the P generation, a tall plant was crossed with a short plant. If alleles did not segregate during gamete
formation, all of the F2 plants would be tall - correct answer -.
Genes located on homologous chromosomes may have alternate forms that control different forms of a
trait. These alternative forms of a gene are called alleles - correct answer -.
If two heterozygous individuals are crossed, what percent of their offspring are also expected to be
heterozygous? - correct answer -50
Gregor Mendel concluded that traits are inherited through the passing of factors from parents to
offspring - correct answer -.
The passing on of traits from parents to offspring is called - correct answer -Heredity
The chemical factors that determine traits are called - correct answer -Genes
A punnet square does not show you the actual results of a genetic cross - correct answer -.
A tall plant is crossed wuth a short plant. If the tall F1 pea plants are allowed to self-pollinate, some of
the offspring will be tall, and some will be short - correct answer -.
How many different allele combinations would be found in the gametes produced by a pea plant whose
genotype was RrYY? - correct answer -2
In which situation are the phenotype a of F2 offspring expected to follow the ratio of 9:3:3:1? - correct
answer -A dihybrid cross for 2 unlinked traits
Which of the following of found in both DNA and RNA? - correct answer -Phosphate groups, guanine,
and cytosine
