Its a 50/50 so two of there kids will have blue eyes and two will be brown eyes but the children with brown eyes with be heterozygous for blue eyes and same thing with the brown eye children
They consist of double-bond and single bond, according to the type of DNA.
Answer:
1- Presence of phenotypic variation
2- some phenotypic variation due to genetic variation
3- the given trait has an impact on fitness
Explanation:
The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of <u>evolutionary genetics.</u> The mutation will lead to <u>all the bacteria becoming resistant to the antibiotic.</u><u> </u>
Genetic evolution :
Evolutionary genetics examines the relationship between genetic variation and evolutionary change. As a result of the recent expansion in the availability of whole genome sequence data, large amounts of genetic data are being produced at an increasing rate, making programming an indispensable tool for researchers.
The spread of antibiotic resistance among pathogenic bacteria is a straightforward and elegant example of adaptation through natural selection. Through mutations that alter the biological targets of antibiotics or by obtaining resistance genes from other bacteria, microorganisms can develop resistance to antibiotics.
