Shell coiling in some snails has been found to be determined by the genotype of the snail's mother, rather than its own genotype
baherus [9]

Answer:

maternal effects

Explanation:

<em>The correct answer would be maternal effects.</em>

<u>The maternal effect is a genetic phenomenon that is characterized by an organism having the phenotypic expression that is compatible with the genotype of its mother irrespective of the organism's genotype itself.</u>

This condition often occurs as a result of the mother supplying messenger RNA or protein to the egg that results in the formation of a zygote/embryo. Consequently, the genome of the mother dictates the functionality of the molecule in such offspring.

When an antibiotic is __________, some bacteria can survive, and their offspring carry the ability to resist that antibiotic.
aleksklad [387]

When an antibiotic is overused, some bacteria can survive, and their offspring carry the ability to resist that antibiotic and this is known as Multi-drug resistance(MDR) in bacteria.

Antimicrobial resistance to at least one antimicrobial drug in three or more antimicrobial categories is known as multiple drug resistance (MDR), multidrug resistance, or multi-resistance.

Multi-drug resistance in bacteria refers to the ability of some bacteria to survive when an antibiotic is abused or overused and pass that ability to their progeny.

Antimicrobial categories group antimicrobial substances according to the target organisms they are effective against.

Multiple antibiotic-resistant bacteria are the MDR forms that pose the greatest concern to public health; other types include MDR viruses and parasites (resistant to multiple antifungal, antiviral, and antiparasitic drugs of a wide chemical variety).
