Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
Fish are a class of aquatic vertebrates. The combination of gills, fins and the fact that they live only in the water make fish different from all other animals.
Answer:
yes
Explanation:
I think as people, we have to look at everything twice and consider the bad and the good to reqlly get the best result.
The event is called mutation
A mutation is a rare, accidental or induced modification of genetic information in the genome, specifically DNA.Depending on which part of the genome is affected, the consequences of a mutation may vary.
A mutation is said to be hereditary if the mutated genetic sequence is transmitted to the next generation (see germinal mutations).
It is one of the elements of biodiversity and one of the many factors that may be involved in the evolution of the species (for example: production of new protein which help the bacteria to grow in hostile environment like fungi).
Ferns don’t have to be in a tropical setting, but they can.
It’s a bad question.
