Animal Breeding

The video tutorial covers animal breeding, focusing on developing better breeds for human use. It explains inbreeding, its effects, and how outbreeding methods like outcrossing and crossbreeding can overcome these issues. The tutorial also introduces modern biotechnological approaches such as artificial insemination and multiple ovulation embryo transfer technology to enhance breeding efficiency and productivity.

What is the primary goal of animal husbandry?

• To increase the number of animal species

• To reduce the genetic diversity of animals

• To develop better animal breeds for human use

• To preserve endangered animal species

What is a potential negative effect of inbreeding?

• Inbreeding depression

• Increased genetic diversity

• Higher fertility rates

• Improved growth rate

How can inbreeding depression be overcome?

• By increasing the number of generations

• By mating selected animals with unrelated animals of the same breed

• By reducing the number of offspring

• By using only one breed for mating

What is the purpose of crossbreeding?

• To produce a new breed with superior traits of both parents

• To maintain the purity of a single breed

• To increase the number of offspring

• To reduce the economic value of animals

What is an example of interspecific hybridization?

• A mule, offspring of a male donkey and a female horse

• A genetically modified chicken

• A purebred dog

• A high-yielding cow

What is a benefit of artificial insemination in animal breeding?

• It reduces the number of females that can be fertilized

• It allows for the storage and transport of semen

• It decreases the rate of conception

• It requires natural mating

How does multiple ovulation embryo transfer technology help in animal breeding?

• By reducing the number of eggs produced

• By increasing herd size in a short period

• By limiting the number of surrogate mothers

• By decreasing the success rate of fertilization
