Last Answer: "Never! When would it be positive? It's a DEFORMATION!!!"
That's incorrect. Without mutations, evolution could never occur. For example:
Imagine a bird with a very small mouth. The seeds it eats are very large, and many birds die of starvation. Because of a mutation, one bird's mouth is larger than any other's, and it ends up surviving, passing on that "deformed" gene to its offspring who also survive because of their large mouths.
That is just one example of how a mutation can lead to positive evolutionary changes.
What else can I help you with?
The original source of genetic variation that serves as the raw material for natural selection is what?
Generally, mutation.
Serial connection definition?
This connection goes from negative 2 positive which raises the voltage. Thanks!! o.o
What are two types of mutation?
From another angle: beneficial and detrimental.
Why is mutation important to spectation?
Without mutation there can be no evolution. Without evolution there can be no speciation.
A change in the nucleotide base sequence of gene or DNA molecule is called a what?
this is called a mutation
What is a brief definition in mutation?
genetic disorder
Can anyone become a mutant by mutation?
The only way to become a mutant is via a mutation, but a mutation does not guarantee a unique phenotype. (I'm assuming, here, that you're using a biological definition of "mutant" and not a more fanciful definition.)
In your own words write a definition for the word mutation?
mutation: a change in the sequence of DNA to cause a unusal trait
What is the definition of polyploidy mutation?
Polyploidy mutation is a type of mutation that results in an organism having more than two complete sets of chromosomes. This can lead to increased genetic diversity and potentially new traits in the organism.
What is one positive and negative effect of mutation?
One positive effect of mutation is that it can introduce genetic diversity within a population, allowing for greater adaptability to changing environments and potentially leading to evolutionary advancements. Conversely, a negative effect of mutation can be the development of harmful genetic disorders or diseases, which can adversely affect individuals and populations.
Why do you get a positive answer when multiplying two positive integers?
It follows from the definition of multiplication.
What is the best definition of mutation?
A mutation is a change in the DNA sequence of an organism, which can result in alterations to the characteristics or traits of the organism. Mutations can occur spontaneously or be induced by various factors such as chemicals or radiation.
Can an O positive parent have a b negative child?
It is possible (by spontaneous mutation, for example) but unlikely.
Can a number be both natural and positive?
The most common definition of 'natural' numbers is: The counting numbers.According to that definition, all natural numbers are positive.
What is the word for the definition genetic change in population over time?
Long time = evolution. Short time = mutation.
What is the definition of selective reverse mutation?
Selective reverse mutation refers to a process in which a specific mutation that had previously occurred in an organism is corrected or reverted back to the original DNA sequence. This can happen naturally or can be induced by various genetic or environmental factors.
Why is the absolute value always positive?
It's positive by definition. That's what the absolute value is.
