Mendelian Genetics
1.
The units of heredity that determine which traits, or characteristics, that children inherit from their parents
are
a. muscles.
b. genes.
c. birth.
d. zygote.
2.
In your own words, explain Mendel's law of segregation.
3.
Suppose there is a man heterozygous for brown hair (Bb), his wife is homozygous for blond hair (bb), and
their neighbor is homozygous for brown hair (BB). The couple's baby has blond hair. Using your knowledge
of heredity, can the baby be the neighbor's kid? Explain.
4.
What are the alternative forms of genes?
a. alleles
b. genotypes
c. phenotypes
d. inherited patterns
e. traits
5.
Mendel's law of dominance states that
a. an organism will always be stronger than its parents.
b. only the alleles from the male parent will appear in the phenotype of the offspring.
c. traits will disappear from phenotypes during the dominant generation and reappear during the
recessive generation.
d. if an organism inherits two different alleles, only the dominant one will show up in its phenotype.
6.
What is the difference between genotype and phenotype?
7.
When Mendel crossed pea plants, he termed the first generation of offspring as the first
Latin meaning "son."
8.
What is the term for the breeding of parents when only one trait is being investigated?
from
a. law of segregation
b. monohybrid cross
c. dihybrid cross
d. Punnett square
9.
An individual who has two exact copies of an allele is heterozygous.
a. True
b. False
10. When considering different genotypes, what are the three conditions that can exist according to Mendel's
law of segregation?
