Lecture 1: into

Question 1

EIC is

Answer 1

Exercise Induced Collapse (EIC)

Question 2

EIC does what

Answer 2

Affected dogs become weak in hind limbs and collapse after 5-20 minutes of high intensity exercise
Likely gene candidate has been identified – can be tested
EIC is inherited as an autosomal recessive

Question 3

Obesity in labs is caused by

Answer 3

Variant of POMC gene strongly associated with weight and appetite
23% of Labradors are thought to carry at least one copy of the variant
Gene involved in hunger recognition and the feeling of being full after eating
Carrying the variant may make dogs easier to train with food

Question 4

The study of genetics was found in

Answer 4

Study of genetics and how they control the development and maintenance of an organism
1860’s – Gregor Mendel
His observations and quantitative analysis were the foundations of genetics
Pertains to all types of organisms

Question 5

3 main branches of genetics

Answer 5

Transmission (Mendelian)
Molecular
Population

Question 6

Genetics is concerned with

Answer 6

Storage of biological information
How that information is expressed and regulated
How it is transmitted from parents to offspring
How that information is altered

Question 7

Gene is

Answer 7

Hereditary unit
An information storage unit that can be replicated, expressed, regulated and transmitted

Question 8

Genes are made up of and organized into

Answer 8

Genes are made up of DNA
Genes are organized into chromosomes
Different regions of chromosomes represent different hereditary units

Question 9

Genotype is

Answer 9

Genetic make-up
The particular gene(s) associated with a given characteristic / trait

Question 10

Phenotype is

Answer 10

The observable physical or biochemical characteristic
Determined by both genetic makeup and environmental influences
A “breed” is a group of organisms that share a particular phenotype

Question 11

Mitosis is

Answer 11

The genetic material is exactly duplicated and distributed to 2 new nuclei during normal cell growth

Question 12

Meiosis is

Answer 12

This process halves the amount of genetic material in a cell, generally in the formation of gametes for sexual reproduction

Question 13

Mutation is

Answer 13

Altering of DNA

Question 14

Chromosomes are

Answer 14

Packages of genes

Question 15

Genetic map is

Answer 15

How genes are organized on a chromosome

Question 16

Genetic selection is

Answer 16

Selection of parents as breeding stock on the basis of certain inherited characteristics

Question 17

Breed is

Answer 17

A group of related animals who are genotypically and phenotypically similar enough to produce similar offspring when mated together
