A beneficial inherited trait is a characteristic of a creature that is passed down in the DNA of the mother and father, via the sex cells, to the offspring.
Imagine if giraffes all had very short necks, like a horse. They would only have access to the food on low bushes or at the bottom of trees. But, one giraffe, by freak chance (mutation in the DNA) has a slightly elongated neck. Because this giraffe has a longer neck, it can reach higher food. This means that it is less likely to go hungry, as it can reach food that the others cant, and is therefore more likely to survive to be a healthy adult.
The giraffe with a longer neck then reproduces, and the trait is passed on to the offspring. The offspring then mates with others, and the gene is spread around the herd of giraffes. Eventually, all of the giraffes have slightly longer necks, which means they all have to share the same food again.
Then a mutation causes another giraffe to get an EVEN LONGER neck, and the whole process is repeated, until giraffes all end up with really long necks, and the ones with short necks that cannot reach higher food become extict, as they cannot compete with the longer-necked giraffes.

What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
What are characteristics passed from parent to offspring called?
genetic traits
4. Inherited traits are passed down from our parents to us their offspring by the information that is coded in our parents?
genes.
In natural selection what must be true in traits that are passed down through generations?
They must help the organism in it'senvironmentso it may survive andreproduceand pass the trait down. If the trait is undesirable or useless the trait is selected against. Like if the desert was covered in snow, and all the 'prey' animals were out and wondering around. They can see if a 'predator' is coming, because of their orange-light brown color cause it doesn't blend in with the surrounding it isn't goodcamouflage.
Why only mutations in gametes can be passed on to future generations?
Mutations in gametes can be passed on to future generations because gametes are involved in reproduction and carry genetic information that can be inherited by offspring. Somatic mutations, which occur in non-reproductive cells, do not affect the germline and therefore cannot be passed on to future generations.
When are mutations passed on to future generations?
Mutations can be passed on to future generations when they occur in the DNA of germ cells (sperm and egg cells) that are involved in reproduction. These mutations can be inherited by offspring and become a part of their genetic makeup.
What dœs inherited mean?
passed on from many family generations
What happens if a person with mutation reproduce?
If a person with a mutation reproduces, there is a chance that the mutation may be inherited by their offspring. Whether the mutation will be passed on and expressed in future generations depends on the type of mutation and its mode of inheritance. Some mutations are harmful, while others can be neutral or even beneficial.
Why do inherited traits change over time?
Inherited traits can change over time due to genetic mutations, which are alterations in the DNA sequence that can be passed down to future generations. Changes in the environment or selective pressures can also influence the way certain traits are inherited and expressed. Over many generations, these factors can result in variations in inherited traits within a population.
What is a modification of genetic mateirial that will be passed onto future generations?
A modification of genetic material that can be passed on to future generations is called a heritable genetic alteration. This refers to changes in the DNA sequence that are inherited by offspring from their parents. Examples include gene editing techniques like CRISPR-Cas9.
What are inherited trait?
An inherited trait is a charateristic passed from parents to offspring.
Which perspective highlights the reproductive advantages of inherited psychological traits?
The evolutionary perspective highlights the reproductive advantages of inherited psychological traits. It focuses on how certain psychological traits may have been passed down through generations due to their beneficial effects on survival and reproduction.
How many definitions are shown for heritage?
Property that is or can be inherited or something that is passed down from preceding generations, or a tradition.
How will A mutation in what type of cell will be passed on to future generations?
Sperm cell
What must be of traits that are passed down through generations?
Traits that are passed down through the generations must be either culturally or environmentally inculcated or genetically inherited (or some combination of these). Evolutionary Biology concerns itself with genetically inherited traits. In the long term, for genetically inherited traits to continue to be passed down through the generations, they must be at least neutral with regard to reproductive fitness, or advantageous (i.e. they must not be subject to negative selection pressure)
How is albinism inherited and passed down through generations?
Albinism is a genetic condition that is inherited when both parents carry a specific gene mutation. This mutation is passed down through generations in an autosomal recessive pattern, meaning that both parents must pass on the mutated gene for a child to have albinism.
