DNA ligase is like the glue that pieces together DNA. DNA polymerase "unzips" the DNA helix in DNA replication.
Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
The variation in color and markings is beneficial to the orchid plants because it helps the flowers pollinate efficiently (Option C). It is an adaptation.
<h3>What is an adaptation?</h3>
An adaptation is an evolutionary trait that allows an organism to take advantage of survival and/or reproduction.
Orchid color can attract pollinators by mimicking flowers of plant species that live in the same area.
It is an adaptation known as mimetism, which allows them to take an evolutionary advantage.

Answer:
Tan fur helps the mice protect themselves from predators
Explanation:
The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.
