Flashcards in Animal Genetics Deck (15):
1

Phenotype

The outward, physical apperance of an animal

2

Genotype

Genetic makeup of an animal

3

Environmental Factors that may affect the appearance of an animal

-Quantity and quality of feed
-Climate conditions
- Exposure to parasites and diseases
-Type of terrain
-Producer's control over animal

4

Natural Selection

Survival of the fittest; strongest, healthiest, and most powerful survives to spread its genetics

5

Controlled Breeding

Producer crosses 2 parents based on desired outcome

6

Outcrossing

Breeding purebred animals with unrelated purebred animals

7

Cross Breeding

Breeding animals of the same species but of a different breed

8

Hybrid Vigor (Heterosis)

Biological phenomenon which causes crossbreeds to out produce the average of their parents
Stronger animals

9

Chromosome

A long protein strand that allows specific genetic information or traits to be built into or engineered into the genes of a species

10

Allele

a pair of genes that control a specific trait

11

Monohybrid cross

for the estimation of predicted outcome for a single trait

12

Genetic Mutation

Genetic traits not passed on as intended and defects happen

13

Abnormality

Similar to a mutation, only it is caused by something in the environment

14

Differentiation

As the embryo begins to grow and develop, cells differentiate
Some cells develop into muscle, bone, skin, ect

15
