Some dairy farmers want to increase the amount of milk produced by their cows. How can the farmers use selective breeding to increase milk production?
By limiting the number of offspring per cow
By allowing the cows to select their mates
By breeding cows that are high milk producers
By increasing the age of the cows that are bred
Organisms with desirable traits can be produced through selective breeding and natural selection. Decide whether the examples on the right are examples of traits produced through selective breeding or natural selection.
Selective Breeding
Natural Selection
What is one difference between natural selection and selective breeding?
With natural selection, the genetic makeup of an organism is different than it's parents. With selective breeding the genetic makeup is identical to its' parent.
Once a trait helps a species survive, the time it takes for that trait to become apart of the population is much faster with natural selection.
Traits developed through natural selection are influenced by pressures from the environment. Organisms that are produced through selective breeding have traits selected by humans that may or may not be related to environmental pressures.
Natural selection can only occur when organisms are chosen and produce offspring. Selective breeding allows organisms to select a mate who is the best adapted to its' environment.
Selective breeding is an effective way to produce organisms that have desirable traits. After several generations of selective breeding, an organism can be produced consistently with certain traits. The disadvantage to the offspring can be
they may be unable to reproduce.
offspring from one organism that is selectively bred cannot breed with another organism.
they are not as genetically diverse as organisms who were not selectively bred.
they produce less offspring.
Help Please!!!!!
I think...
1. A
2. idk
3. C
4. A
By breeding cows that are high milk producers
What's to the right?
Traits developed through natural selection are influenced by pressures from the environment. Organisms that are produced through selective breeding have traits selected by humans that may or may not be related to environmental pressures.
they are not as genetically diverse as organisms who were not selectively bred.
thank you sm for responding but I STILL DONT KNOW :((((
The questions were answered. I just have you the answers to the questions without putting a number next to them.
Just for clarification, what is to the right reversed to this question:
Decide whether the examples on the right are examples of traits produced through selective breeding or natural selection
By choosing cows that are high milk produce.
To increase milk production, dairy farmers can use selective breeding by breeding cows that are high milk producers. This involves selecting cows that have a proven track record of producing large amounts of milk and mating them to produce offspring with similar traits.
For the second question, determining whether a trait is a result of selective breeding or natural selection involves understanding the origin of the trait. Selective breeding refers to humans intentionally choosing organisms with desirable traits to produce offspring with those traits. Natural selection, on the other hand, is the process by which traits that contribute to an organism's survival and reproduction become more common in a population over time. So, examples on the right that are a result of selective breeding would be selective breeding, and examples that resulted from the pressures of the environment would be natural selection.
Regarding the difference between natural selection and selective breeding, one difference is that in natural selection, the genetic makeup of an organism is different from its parents, whereas in selective breeding, the genetic makeup is typically identical or very similar to its parents. Additionally, traits developed through natural selection are influenced by pressures from the environment, while traits selected through selective breeding may or may not be related to environmental pressures.
Lastly, the disadvantage of offspring from selectively bred organisms is that they are not as genetically diverse as organisms that were not selectively bred. This reduced genetic diversity can make them more susceptible to diseases or environmental changes. It is important to maintain genetic diversity to ensure the long-term health and adaptability of a population.
Based on your answers, it seems you have correctly identified options 1 and 3. However, option 2 is incorrect, as the traits produced through natural selection are not influenced by the organisms' choices of mates, but rather by the survival and reproductive success of individuals with certain traits. Option 4 is also incorrect, as selective breeding does not necessarily involve selecting a mate based on their adaptation to the environment.
Correct answers:
1. By breeding cows that are high milk producers
2. Examples on the right: Selective Breeding
3. Traits developed through natural selection are influenced by pressures from the environment. Organisms that are produced through selective breeding have traits selected by humans that may or may not be related to environmental pressures.
4. They are not as genetically diverse as organisms who were not selectively bred.
