An organism is for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s , or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are .
Mendel’s law of governs which allele is expressed in an individual.

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
