Question

what is a Plasmid
crosses between parents of different species, but that are genetically close enough to produce an offspring
Procedure used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and applying an electrical voltage to the gel
small, circular piece of DNA located in the cytoplasm of many bacteria
There are more than 2 alleles in the gene pool to choose from, but only 2 are inherited

Answer 1

- Plasmid: a small, circular, extrachromosomal piece of DNA found in the cytoplasm of many bacteria (and some eukaryotes). Plasmids replicate independently of the chromosome and often carry genes (e.g., antibiotic-resistance or metabolic genes) that can be transferred between cells.

- Crosses between parents of different species but genetically close enough to produce an offspring: an interspecific hybrid (often simply called a hybrid).

- Procedure to separate and analyze DNA fragments by placing them in a porous gel and applying an electrical field: gel electrophoresis.

- Situation where there are more than two alleles for a gene in the population, but each individual inherits only two: multiple alleles (multiple-allele inheritance).
