What is different in phenotypes of an individual from those in the same species?
Phenotypes are the characteristics of the genes that are most dominant, and can represent themselves. Species have many different genes for example, you dont have the exact same genes as your best friend, and thus, producing different phenotypes which is why you look different... However, you do have may similar genes that make you part of that species.
How can genes be altered and combined to create genetic variation within a species?
Through different types of mutations.ChromosomalinsertiondeletiontranslocationinversionGenesubstitutioninsertiondeletion
How is human DNA different form the DNA of a chimpanzee and different from the DNA of a goldfish?
its really minutely different. like 99% of it is the same, but the remaining 1% includes genes that really make difference and seperates us as distinct species. we express different genes.
Adaptations of species are determined by the genes contained in the DNA code?
No, the genotypes of species are determined by the genes contained in the DNA code, not adaptation.
What are the 4 characteristics of genes. Which one do you think is the most important?
Genes have four main structural parts - the promoter, introns, exons and the termination site (or recognition site for Rho protein). They are all very important (since exons contain the code for creating products, these could be called more important than introns - although it is believed introns still have an important role). Genes are how you get your own physical characteristics. They are the fundamental unit of heredity. Genes are found on chromosomes made of DNA. Different genes determine different characteristics, or traits, of an organism.
What are the two most important factors in determining ecosystem diversity?
Sexual reproduction mixes the genetic inheritance for each generation;Different environmental pressures on different species - only those species that have the best characteristics to survive the environmental pressures will survive long enough to reproduce and leave their genes for the next generation.

How many genes are there in DNA?
Different species have different numbers of genes. About 1.5% of human DNA is genes - and it is estimated that there are around 23,000 protein-coding genes.
Why fertilized human is important?
Fertilization is important so species can have genetic variation. It is also important so the species can pass on their genes.
What are the importance of evolution in the management of resources?
Evolution adapts organisms via their dna and genes over periods of time for different circumstances. Survival of the fittest keeps the fittest members of a species alive to reproduce and pass on the genes that made them survive and over time the genes of the species will change to be able to survive better. So the ancestral species could go extinct so fish could into species intelligent enough to avoid nets and hook/lures and over time we won't be able to catch them and will need to move on.
Why is it necessary to use the same genes from different species when producing hybrid DNA?
It is necessary to use the same genes from different species when producing hybrid DNA to realize better resistance.
Why can isolation cause differences in species and possibly lead to new species?
Their genes might mutate in different directions, so once their genes do not match up, a new species will be made.

Is survival in the genes?
The process of evolution tends to produce organisms whose genes contribute to the survival of the organism. If an organism has genes which impede or prevent survival, then the organism is less likely to survive. A species with such genetics would die out.
What is produced by combining genes from different sources?
When combining genes from different sources, whether it be in the plant or animal kingdoms the outcome will result in what is known as a hybrid, or new species with the potential to carry the genes of both original specimens.
Why are two individuals in the same species always different?
offspring recieve different combinations of genes from each parent.
According to modern evolutionary theory genes responsible for new traits that help a species survive in a particular environment will usually?
increase in frequency
