Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. Overall, the main sources of genetic variation are the formation of new alleles, the altering of gene number or position, rapid reproduction, and sexual reproduction.
Q. Are hybrids are often hardier than either of the parents?
-The continued breeding of individuals with similar characteristics. Are hybrids often hardier than either of their parents? -They can cross recessive alleles causing blindness, and joint deformities in dogs.

Q. What are two methods used by breeders to increase the rate of mutation?
Most mutation breeders induce random changes in DNA by using ionizing radiation or mutagenic chemicals, such as ethyl methane sulfonate, to increase the rate and frequency of the mutation process.
Q. What is the continued breeding of individuals with similar characteristics?
*Inbreeding is the continued breeding of individuals with similar characteristics.
Q. Why are radiation and chemicals useful techniques for producing mutant bacteria?
– Radiation and chemicals can increase the mutation rate. Why are radiation and chemicals useful techniques for producing mutant bacteria? The small size of bacteria enables millions of organisms to be treated at the same. time, thus increasing the chances of producing a useful mutant.
Q. What is a cross between dissimilar individuals to bring together?
a cross between dissimilar individuals to bring together their best characteristics is called. hybridization. crossing individuals with similar characteristics so that those characteristics will appear in the. inbreeding. You just studied 10 terms!
Q. Does a hybrid plant have all the characteristics of both its parents?
b.A hybrid plant has all the characteristics of both its parents. Hybridization is used to produce new varieties of plants and animals.
Q. What is the total amount of DNA in a cell called?
The total DNA in a cell is called the genome.
