Scientist rely on <em>Biology </em>concepts when researching crop production and medicine.
Answer:
Explanation:
4 types of mutation:
Germline mutations occur in gametes. Somatic mutations occur in other body cells.
Chromosomal alterations are mutations that change chromosome structure.
Point mutations change a single nucleotide.
Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame.
3 more:
Over a lifetime our DNA can undergo changes or 'mutations?' in the sequence of bases?, A, C, G and T.
This results in changes in the proteins that are made.
Mutations can occur during DNA replication if errors are made and not corrected in time.
bottleneck effect --- > A disease wipes out almost 90% of a population of birds, but the species adapts, and after 5 years its numbers increase dramatically.
gene flow ---> A population of rats travels on a cargo ship and mate with rats in a new region.
founder effect ---> Biologists introduce a small population of lizards on an island as part of a conservation effort.
mutation ---> A change in a DNA sequence causes a lizard to develop a darker skin color, which helps it hide from predators.
Answer:
Explanation:
According to hardy-weinberg principle that says in a large random mating population in the absence of migration,mutation and selection the gene and genotype frequency remains constant.
In a large random mating population the frequency of an Allele for white fur will remains in the population when there is no migration,mutation, or selection but the organism mate at random leading to production of offspring with similar Allele with there parents but when the population is small and random mating occur some allele will be selected against and lost in the population due to flunctuation in the population.
