1.
True or false
All
dogs carry multiple mutations: a genetic test is used to look at a
specific mutation.
True
False |

2.
True or false. If my animal has the mutation for RD, then that is the
only defect that he/she has.
True
False |
|
3.
Chromosomes are:
made of protein, and
reside in pairs in the nucleus
made of DNA, and
reside in the nucleus in pairs (one from the sire and one from the dam) |
|
4.
Proteins are:
The basic unit of inheritance
The products that are coded for by DNA |
|
5.
Dogs have:
39
78
19
Pairs of chromosomes |
|
6.
In order have a genetic disease for a recessive mutation the animal
must:
have only one bad copy of a gene
have two bad copies of a gene |
|
7.
My dog is a carrier of the mutation that causes RD. This means that:
he/she should be
eliminated from my breeding program.
he/she should be bred
with a partner whose traits complement my animal, and that all of the
offspring should be tested
to determine if clear puppies have been produced to continue to enhance
my breeding program. |
|
8.
RD is inherited as:
a simple recessive trait
a dominant mutation
that is inherited with incomplete penetrance, meaning that animals with
no clinical signs of the disease
can suddenly produce affected progeny |
