What can predict whether a mutation in a human skin cell can be passed to its offspring?
A mutation in a human skin cannot be passed on to an offspring, since it is only a somatic mutation which is acquired. The mutation that can be passed on to an offspring is called a germline mutation, which happens in the egg and sperm.
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed on to the offspring?
Lamarck.
What is true of adaptations?
They are passed along to offspring - APEX
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed to the offspring?
John-Baptiste Lamark
How can you use the concept of genetic inheritance to disprove Lamark's idea of the inheritance of acquired characteristics?
Lamarck's theory is disproved through many different examples of acquired characteristics. Anything that happens to a parent would be passed on to the offspring. Acoording to Lamarck, a parent that has tattoos would pass on the tattoos to the offspring. Loss of limb, injuries, cosmetic surgery or anything that changed in the parents would manifest in the offspring. This is not the case. Acquired characteristics are not passed on to offspring unless they change the gene sequence of the sex cells. Parents do not give physical characteristics to offspring, but do give the coding for those characteristics. The gene passes on the trait.
Who proposed the acquired traits could be passed on to an organisms offspring?
Lamark
Which is true about adaptions?
They are passed along to offspring.
How did Lamarck propose that species change over time?
Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species
Lamarck proposed that organisms?
Lamarck proposed that organisms developed new features as a result of a 'inner urge' for improvement and that they passed on these improvements to their young/offspring. He did not accept that animals could become extinct.
What was Lamarck's principle of use and disuse?
Lamarck proposed that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species
The mutations that breeders induce in organisms are passed on to the organisms?
offspring
Explain lamarck principle of use and disuse?
Lamarck proposed that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species
Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
what is Adaptation about?
They are genetically acquired traits They are passed along to offspring
Is the process through which traits are passed from parent to offspring?
acquired characteristics
Who proposed that acquired traits could be passed on to offspring?
This is a theory that states that some characteristics of an individual are acquired as opposed to inherited. For example, some frogs have mutations because of pollutants in their environment, whereas a person who has blue eyes probably has them because they inherited them from their parents.
