Using selective breeding is exactly how people produced the different Dog Breeds. They discovered dogs that had the characteristics or skills they wanted and bred them.
I'm working on the same worksheet as you. The answer is shared dominance and the answer to the other is selective breeding.
The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated
they were different.
A male Yorkie should be at least a year old to start breeding, and it's better to wait until he is closer to two. This gives him time to mature and allows you to make sure he does not develop any genetic faults that he might pass on to his puppies.
The average lifespan of a bulldog is 8-10 years. The reason why the lifespan of a bulldog is so short is because selective breeding has caused them to develop certain health issues. Many of these health issues are directly related to the certain characteristic of the bulldog breed such as the short snout making them more likely to have breathing problems, and their stocky bodies make them more susceptible to bloat.
Ultimately the sole cause of different species is restricted breeding. Males and females of one species will only mate with males and females of the same species. Now there may be a secondary factor that is the main cause, such as geographic isolation. The two species develop separately because there is a mountain range in between them and the males of each type can't get access to the females of the other type. But as you can see it is the restricted breeding that ultimately does it. Now for two species of stickleback in the same lake. It may be that the females are finicky in their chose of mates and prefer male with a certain colour pattern, or they prefer nests built at a certain depth which males have an inclination to build at different heights.

Is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits. So males and females will sexually reproduce and have an offspring together.
It is called selective breeding.
Selective breeding is the process in which two animals from the same species reproduce due to useful characteristics. Two animals with a certain type of characteristic are bred together to produce offspring. Then the offspring with the most useful characteristic breeds with another offspring to produce more offspring. This process continues for generations until the offspring consistently have the useful characteristic farmers or scientists are looking for. Cross-breeding is a type of selective breeding except with animals from two organisms from the same species but not the same breed. Selective breeding is one of the most common causes for a wide range of breeds in animals and varieties in plants. this is incorrectIt is the process which humans use animal breeding and plant breeding to selectively develop particular characteristics by choosing which typically animal or plant males and females will sexually reproduce and have offspring together
selective breeding, cloning, and genetic engineering are three methods for developing organisms with desirable traits >,< i have a cold :]
Because they do
Lateral buds develop generally when apical dominance is terminated
to determine its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods.
You will have to wait until the fish is in breeding condition during the breeding season.(spring time). Then, if the fish is male, it will develop white pimple like structures on its gill plates and maybe its pectoral fins too. If it is a female it will develop a chubby tummy.
The phenotypes were easily identifiable. It was possible to develop true breeding varieties for each character because there character traits varied in an either or fashion. The characters were also located on different chromosomes.
It really depends. It usually happens soon after the breeding or before the pups are born.
