The continued breeding of individuals with similar characteristics?
hybridization
What is mass selection in plant breeding?
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding
Why is it important to know the mode of reproduction of crops in plant breeding?
to determine its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods.
What is the definiton of '' selective breeding''?
Selective breeding is where you breed animals or plants in such a way as to increase the desirable traits, or characteristics. By specifically selecting breeding partners with high levels of these desirable traits, the likelihood of the offspring having these traits increases. Over several generations, these desirable traits become more and more profound. For example, if farmers take only the best sheep for breeding, then they can be more assured that future generations of sheep will have the same or even improved characteristics. Selective breeding also works in a similar way when developing new crops, or the breeding of dogs for example. Its all about human intervention, where the breeding partners are chosen (or selected) by people.
Scientists determine evolutionary relationships by looking at breeding behavior geological distribution and structural similarities between organisms true or false?
It is true that scientists determine evolutionary relationships by looking at breeding behavior, geological distribution, and structural similarities between organisms. Scientists can use other criteria to determine evolutionary relationships.
Characteristics of the agriculture revolution?
Characteristics of the Agricultural Revolution. >Livestock Breeding.
The continued breeding of individuals with similar characteristics?
hybridization
What is pisciculture Can you define it?
Pisciculture is the rearing and breeding of fishes under controlled condition.
When human change the physical characteristics of organism's what type of selection is it?
Breeding.
What is mass selection in plant breeding?
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding
Why is classification flexible?
Classification can be flexible depending on the animals breeding, physical characteristics.
What are the advantages and disadvantages of animal breeding on the environment?
The advantage of animal breeding is that animals that are close to extinction can be repopulated. The disadvantage of animal breeding is over population of common animal species.
What are perfect guinea pig breeding conditions?
cozy big environment
What is true-breeding?
Referring to organisms for which sexual reproduction produces offspring with inherited traits identical to those of the parents. The organisms are homozygous for the characteristics under consideration.
What is the crossing of plants or animals for a specific trait such as height?
The simplest answer is selective breeding. Selection for specific/desired traits can be used to improve breed uniformity or create a breed. This is most often accomplished through both inbreeding and line breeding to "set"characteristics in a population. The term "Set" is essentially where the desired characteristic can only be expressed one way: another word for this is homozygous. It is easiest to "set" recessive traits since animals with the dominant characteristic can be easily removed from the breeding program. Characteristics that are polygenic (controlled by multiple genes) are the most difficult to "set".
What is a breeding experiment where a single trait controlled by two alleles is examined called?
monohybrid cross
What concept is selectively breeding plants and animals to accentuate certain characteristics?
artificial selection
