Mutations. Definition. A Mutationoccurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed
<h2>Evolutionary analysis of organisms</h2>
Explanation:
- Some organisms, which were characterized together determined to genetically very different .
- Using the analysis of RNA developed by Carl Woese, scientists are now able to classify the human evolution
- living things based on genetic information instead of expressed characteristics.
- Genetic information is more specific and can give clues as to the evolutionary ancestry of organisms.
- That is the reason adding of various domains in previous system of classification is allowed for a comparison of species genetic code

Answer:
1:1:1:1 walnut comb
Explanation:
If a cross is made between a female who is RRpp (rose comb) and a male who is rrPP (pea comb) then:
P: RRpp x rrPP
F1: RrPp RrPp RrPp RrPp
This means that all of the offspring in F1 generation will have heterozygous genotype (at both loci). Since it contains both dominant alleles, the phenotype is walnut comb.
