A red flowered sweet pea plant is crossed with a white flowered sweet pea plant. All of the offsprings are pink. what is the inheritance pattern being expressed

The inheritance pattern is incomplete dominance

Explanation: Incomplete dominance is a heterozygous or intermediate condition in which one of the two alleles at a gene locus for a specific trait is not completely expressed over its paired allele. One of the two alleles for a particular trait is not completely dominant over the other allele paired with. Incomplete dominance results in another (a third) phenotype in which the expressed physical trait is a blend of the traits of the two incomplete dominant alleles.

The most valid hypothesis for explaining the natural selection of bacteria is that of Dominique.

Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).
