If the purple plant was homozygous dominate then it can only pass along a dominate allele to its offspring so despite the genotype of the other parent 100% of the offspring will reprsent a purple phenotype.
When the two atoms are split
Answer:
Genetic drift
Explanation:
Genetic drift is an evolutionary mechanism that changes the allele frequency by random sampling (by chance). This type of mechanism has the major impact when population is hit by a natural disaster. As a consequence, the population becomes reduced in size and some alleles might be lost (such as that for for orange crests). The genetic variability is decreased.
Answer:It is a gene that has thousands of different forms.
