Answer:
loss of genetic diversity
Explanation:
Artificial selection, also known as selective breeding, refers to the identification by humans of desirable phenotypic features (traits) in plants and animals and the subsequent breeding procedures to enhance and perpetuate these traits in offspring. As a consequence of artificial selection, future generations of selectively bred animals/plants will share favorable gene variants (alleles), thereby genetic diversity will decrease in the population. This reduction in the gene pool will affect genetic progress and consequently also breeding programs in the future.
Because cotyledons are meant to store reserve food for the developing seedling before it develops its own green leaves for photosynthesis
In population genetics, directional selection is a mode of natural selection in which an extreme phenotype is favored over other phenotype, causing the allele frequency to shift over time in the direction of that phenotype
