Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheri

zloy xaker [14]

Answer:

Co-dominance

Explanation:

Considering the allele for red pigment as CR and that for a white pigment CW, a pink flower will equally express both the pigments in its phenotype and will thus have a genotype of CR CW.

Crossing CR CW × CR CW you'll get,

25% CR CR - red flowers

50% CR CW - pink flowers

25% CW CW - white flowers

Zielflug [23.3K]

Answer and Explanation:

allopatric speciation: occurs when a population becomes isolated by a geographic barrier, becomes a new species as it accumulates changes by natural selection or genetic drift. Also known as geographic speciation.
sympatric speciation: a new species that may arise as mating and gene flow are reduced between populations that share the same area. In other words, a group of people from the same ancestral population that may evolve differently until they no longer interbreed and develop into a entirely different species.
polypoid speciation: mostly commonly occurs in plants, where an accident in cell division results in extra set of chromosomes. This has been a major source of speciation in the angiosperms. Polypoidity increases biodiversity and a it is a source of new genetic material for evolution.
Both allopatric speciation and sympatric speciation depends on the establishment of reproductive barriers, which prevents gene flow between a new species and its parent species. Reproductive barriers may arise due to geographical, behavorial, psychological or genetic differences which may prevent species to breed successfully with related species.
Adaptive radiation: occurs when a species gives rise to many new species after colonizing a region with diverse habitats. It is a rapid increase in a number of species from a single common ancestor.

A chemical equation describes the reaction…

Simora [160]

Answer:

alright Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.

so Reactants → Products. The arrow (→) shows the direction in which the reaction occurs. If the arrow were reversed, the products would become reactants.
