BIOD 210 Module 2 Exam
, Dominant genes are usually linked to the male sex chromosomes.
Correct!
Mendel’s label of “unit factors” are what we now refer to as genes.
Genetic characteristics are controlled by unit factors that exist as
individual entities.
Question 2 pts
True or False: A dominant gene will always cause the expression
of a dominant phenotype in the case of complete dominance.
Correct!
True
False
Question 3 pts
People with sickle-cell disease can become very sick under what
conditions?
Desert environments
Correct! High altitude
:
, Low altitude
Humid environments
Question 4 pts
A homozygous long-haired cat is bred with a homozygous short-
haired cat. Assuming that the gene for long hair is completely
dominant, what are the chances of the F1 offspring being short-
haired?
Your Answer:
0%
0%; All offspring will be heterozygous long-haired.
Question 5 pts
A dog breeder is looking to cross a long-haired female dog with a
short-haired male dog. The gene for hair length has incomplete
dominance. By crossing the F1 offspring, what percentage of the
F2 generation are predicted to be medium-haired?
