1
The different forms of a gene contributed by each parent is called
genetics.
an allele.
a recessive trait.
a dominant trait.
2
What is a gamete?
An alternate form of a gene.
An egg or sperm.
The term for the offspring between two different parents.
The result of true-breeding.
3
Where are chromosomes found?
In genes.
In alleles.
In the nucleus.
In the DNA.
4
The principle of dominance states that
alleles are neither dominant nor recessive
all alleles are recessive
some alleles are dominant and others are recessive
all alleles are dominant
5
Gregor Mendel's principles of genetics applies to
all organisms
plants only
pea plants only
animals only
6
The likelihood that a particular event will occur is referred to as
Probability.
Punnett Squares.
Statistics.
mathematics.
7
An organism possessing the alleles ff for freckles would be considered
heterozygous.
homozygous.
8
Organisms that have identical alleles for a particular trait are called
hybrids.
homozygous.
recessive.
heterozygous.
9
When Mendel crossed the F1 generation peas, he found that the recessive trait had disappeared.
True.
False.
10
If a pea plant's alleles for height are tt, what is true of its parents?
both parents are tall, one is hetero the other homo
both parents contributed a dominant allele
both parents were short
both parents contributed a recessive allele
11
What does the term "homologous" mean?
Having the same parents (true-breeding).
Undergoing the same number of divisions.
Dividing at the same time.
Having the same genes at the same place on a chromosome.
12
The offspring of crosses between different parents are called
clones.
homozygotes.
hybrids.
true bred offspring.
13
The principles of probability can be used to
determine the actual outcomes in genetic crosses
predict traits of the offspring produced by genetic crosses
decide which organisms are best to use in genetic crosses
predict traits of the parents used in genetic crosses
14
A specific characteristic, such as color or size, is called
DNA.
a gene.
a trait.
an allele.
15
Is it possible to have the same phenotype with another person, but a different genotype?
No.
Yes.
16
Gregor Mendel concluded that traits are
inheritedby the passing of factors from parents to offspring
determined by dominant factors only
not inherited by offspring
determined by recessive factors only
17
What is the approximate probability that a human offspring will be male?
75%
25%
50%
10%
18
What is the probability of rolling a dice and landing on 1?
1/2
2/3
1/4
1/6
19
When Mendel crossed a tall plant with a short plant, the F1 plants inherited
tall allele from 1 parent & allele for short from 1 parent
they were true-breeding like their parents
an allele for shortness from each parent
an allele for tallness from each parent
