In the common daisy, genes A and B control flower color. Both genes have a dominant allele (A or B) and a recessive allele (a or b). At least one copy of each dominant allele is required for flowers to be colorful instead of white. The inheritance pattern of daisy flower color provides an example of what type of gene interaction?

Epistasis

Explanation:

In epistasis or epistatic gene interaction, alleles in a particular locus interact with allele at another locus to bring about a phenotype.

Most of the time, the interaction usually comes in the form of suppression or modification of an allele on a particular locus by an allele in another locus.

In this case, gene A and B controls the phenotypic expression of flower colours in common daisy. The presence of either or both makes the flowers of common daisy to be colourful while the absence of both makes the flowers to be white phenotypically.

The presence of either or both of A and B modify the expression of the gene that is responsible for flower colour. This is a good illustration of epistatic gene interaction.

the national environmental policy act (nepa) is a united states environmental law that promotes the enhancement of the environment and established the president's council on environmental quality (ceq). the law was enacted on january 1, 1970. to date, more than 100 nations around the world have enacted national environmental policies modeled after nepa.

brain development. a child's brain undergoes an amazing period of development from birth to three—producing more than a million neural connections each second. the development of the brain is influenced by many factors, including a child's relationships, experiences and environment.
