Selective breeding Flashcards
Give three ways selective breeding can benefit humans?
Dog or cat breeders can be bred to get desirable characteristics in order to get higher demand and sell them for more.
Farm animals can be bred to get more meat and milk per animal.
Fruits and vegetables have been bred to make them more appealing to people as well as to make them larger or have more flesh inside than what they had before humans bred them.
What characteristic have belgian blues been bred for.
They have been bred for the largest muscles possible and more specifically for the gene that regulates muscle growth to not work properly.
Why have belgian blues been bred to be muscular?
The more muscles they have means the more meat they produce.
Artificial insemination is used so
Artificial insemination is used because then scientists can get semen from a cow with the best characteristics that they are looking for as well as it being cheaper to do than if they bought a bull.
Explain in 5 points how belgian blues have been bred
Two cows are selected with the strongest muscles,
They are both bred together,
The strongest of the offspring is bred with another strong cow,
The process is repeated over many generations,
Eventually belgian blues are produced.
