1. These four factors can effect ways evolution occur:
<span>1.) Mutation
2.) selection
3.) Gene Flow
4.) Genetic Drift
2. </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.
In population genetics, gene flow is the transfer of alleles or genes from one population to another.
<span>Genetic drift is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>
Its b. Ecosystem
Population is the number of a species in an area, it has nothing to do with physical characteristics.
Abiotic is just an adjective meaning not alive
Competition is just the interactions between organisms in the struggle for food, water, space, mates, and many other things again not physical characteristics
Answer:
1) M1 is heterozygous since it contains 2 bands, which means that it contains one recessive and one dominant allele
P1 is homozygous for this locus, since it contains a single band or is known to be homozygous for the locus or gene.
P2 is hetozygous for this locus because two bands appear in which each band represents one allele for the gene.
ChildC contains two gel bands, representing two alleles and is therefore heterozygous
P1 is the father of the child C1, if we look at the gel, each father shows a similar band, one coinciding with the mother and the second with the father p1
As for the paternity study, the PCR test is not useful, since it provides asymmetric results, thus only one strand information will be provided, and because the DNA is double-stranded, a more complete study is required.:

Hope I Helped You!!! :-)
Have A Good Day!!!
