What is hybridization in farm animal improvement?
Breeding animals of the same genetic background
Breeding animals of different genetic backgrounds
Raising animals in hybrid environments
Crossbreeding animals with wild species
What is the primary advantage of hybridization in livestock farming?
Predictable offspring traits
Reduced genetic diversity
Increased productivity
Lower initial costs
What term is used to describe the phenomenon where hybrid offspring exhibit better traits than both parent breeds?
Heterosis
Inbreeding
Genetic drift
Homozygosity
What is a potential disadvantage of hybridization in farm animals?
Increased predictability of traits
Loss of genetic diversity
Reduced initial costs
Enhanced fertility
Why is genetic diversity important in livestock breeding?
It simplifies breeding programs
It reduces the need for hybridization
It lowers the risk of inbreeding and genetic problems
It ensures consistent trait inheritance
What is selective breeding in farm animal improvement?
Breeding animals without any specific goals
Breeding animals randomly
Breeding animals with a focus on desired traits
Breeding animals for immediate profit
What advantage does selective breeding offer in shaping the next generation of farm animals?
Increased genetic constraints
Reduced trait consistency
Control over desirable traits
Rapid genetic progress
What potential drawback of selective breeding is mentioned in the discussion?
Slow progress
Inbreeding prevention
Genetic diversity improvement
Complexity for small-scale farmers
In selective breeding, what can happen if farmers narrow their focus too much on specific traits?
Rapid genetic progress
Increased genetic diversity
Inbreeding
Reduced trait consistency
What is one key requirement for successful breeding programs?
Impatience
Lack of resources
Long-term commitment
Random selection of parents
