VERIFIED ANSWERS AND COMPLETE EXAM PREP
• Why did Mendel use a pea plant for his studies? -✓✓ANSWER: - Easy to grow
and breed
- Self-fertilizing
- Easy to cross-breed
• A __________ cross occurs when two pure individual parental strains are mated
that contrast ONLY in the trait that is being observed -✓✓ANSWER: monohybrid
• In genetics, _______ refers to the original parental generation -✓✓ANSWER: P1
• The first set of offspring from the parents are called the ___ generation, which
stands for ______________. -✓✓ANSWER: F1 , first filial generation
• The term _____________ is used to describe the physical manifestation of any
trait -✓✓ANSWER: phenotype
• In the second generation of a heterozygous monohybrid cross, what percentage
of the offspring have the dominant phenotype? recessive? -✓✓ANSWER: 75%,
25%
the ratio is 3:1
• Define gene -✓✓ANSWER: a gene is defined as a unit of heredity that is
transferred from a parent to offspring and is held to determine some
characteristic of the offspring
, • _________ are simply variations of a given gene -✓✓ANSWER: Alleles
• Explain Mendel's 9:3:3:1 dihybrid ratio -✓✓ANSWER: If F1 generation of a
dihybrid cross is crossed, it will result in the 9:3:3:1 ratio of offspring
• The ___________________________________ in genetics states that "the
probability of two or more independent events occurring simultaneously is equal
to the product of their individual probabilities -✓✓ANSWER: product law of
probabilities
often 3/4 * 1/4 in some frequency
• in ___________________________, a single phenotype is affected by more
than a single gene -✓✓ANSWER: gene interaction
• In the case of a _________________, the mutation in a gene results in a total
loss of the gene's function -✓✓ANSWER: null allele
• The phenomenon of an intermediate phenotype of the parental strains is known
as ________________
give an example of this -✓✓ANSWER: incomplete or partial dominance
a white flower + red flower creating pink flower offspring
• Incomplete dominance ratio -✓✓ANSWER: 1:2:1
