Hello students in this question they have asked about the type of variation that is passed into the offspring.
00:08
The first statement given is any trait that an organism picks up during its lifetime are passed into the offspring.
00:35
They have asked to justify whether this is true or false.
00:39
This statement is false as the trait that an organism picks up during its lifetime are said to be the acquired traits.
00:56
These acquired traits are the characteristics that are gained by an organism after birth as a result of external influences or its own activities, which can change its structure or function.
01:12
Hence, these acquired traits cannot be inherited and they are not passed to the offspring.
01:20
The next statement is, only the characteristics that are beneficial during an organism's lifetime is passed to the offspring.
01:54
This is also false as we know the principle of natural selection which means that the traits that offer an advantage will most likely be passed to the offspring and individuals with those traits have a better chance of surviving.
02:25
But in this statement it is given that only the characters that are besters that are best, beneficial during the organism's lifetime is passed.
02:35
It is not a compulsory rule that only the beneficial traits are passed.
02:41
However, other traits are also passed to the offspring...
