They are two different patterns
Selective breeding is where humans choose individual of the same species that have a trait that favors economic growth or any other benefits, then breeding these favorable species until most of the population are the species with the favorable genes. Meanwhile, genetic engineering is where human alters, changes, inserts DNA to modify organisms.
Therefore, one major difference is that selective breeding does not include altering the DNA, while genetic engineering is the altering of DNA.
It is the first one. I just answered this.
Answer:
Traits are determined by an individual's genotype, the summation of the genes in our DNA. A gene is a portion of a chromosome. A chromosome is composed of DNA and contains the genetic material for an organism.Genes Have Alleles
, The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.
