In a species of tropical fish, e colorful orange end black variety called montezuma occurs. when two montezu- mas, are crossed, 2/3 of the progeny are montezuma, and 1/3 are the wild-type, dark grayish green color. montezuma is e single- gene trait, end montezuma fish are never true-breeding. a. explain the inheritance pattern seen here end show how your explanation accounts for the phenotypic ratios given. b. in this same species, the morphology of the dorsal fin is altered from normal to ruffled by homozygos- ity for a recessive allele designated f whet progeny would you expect to obtain, end in what proportions, from the cross of e montezuma fish homozy- gous for normal fins to a green, ruffled fish? c. whet phenotypic ratios of progeny would be expected from the crossing of two of the montezuma progeny from part b?

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

In the united states there are strict fishing seasons and limits, but not all countries enforce similar laws. in bangladesh there are few if any fishing restrictions. what might be the reason for less restrictions in smaller countries like bangladesh? a) the united states is the only country worried about overfishing. b) the united states wants to limit the supply of fish to increase the price. c) bangladesh and smaller countries have an unlimited supply of fish in their coastal waters. d) small countries, such as bangladesh, are practicing subsistence fishing, taking only the fish needed to survive.
