New allozyme variability in Italian honey bees
The Journal of Heredity
|January 1, 1985
Abstract:
Adult workers of the honey bee, Apis mellifera ligustica, from Italy were assayed for enzyme polymorphism using a variety of electrophoretic conditions. Three polymorphic enzyme systems are described, two of which, malic enzyme and an esterase, were previously unknown in indigenous A. m. ligustica. In addition, a new allozyme for the Mdh locus is reported.

Multiple Allele Traits
For the same gene multiple alleles can interact to influence phenotypes like the shape and protein composition of an individual cells.By studying allele interactions on the molecular and cellular levels researchers can understand the resulting phenotypes and complications of human conditions like sickle cell trait, improving treatment.The ABO blood group system is a common example of multiple alleles in humans. This system includes three alleles called IA, IB, and i alleles, which combine in...
Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
Genetic Variation
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.
