Genetics and Reproduction

How does the DNA in the offspring produced by these methods compare to the DNA in the original organism?

• The offspring contain half of the original chromosomes in each method

• The DNA in the offspring is genetically identical to that of the original organism in both methods

• The offspring produced by method A contain twice the original number of genes while those produced by B contain half the original number of genes

• The number of DNA bases is less than that of the original organism in method A, but more than the original number in method B

One characteristic of all living things (including cells) is that they

• develop organ systems

• maintain internal stability

• produce identical offspring

• synthesize only inorganic matter

This technique pictured is a type of

• Chromatography

• Gel Electrophoresis

• Direct Harvesting

• Genetic Engineering

Which process takes place in both methods A and B

• Meiosis

• Mitosis

• Fertilization

• Recombination

Which specific chemicals are needed to carry out the process shown in A?

• Receptor molecules

• Carbohydrates

• Enzymes

• Starch molecules

Production of gametes and support of the fetus normally occur in structures

• 1 and 2

• 2 and 4

• 4 and 5

• 3 and 5

Which sequence represents the path of sperm leaving the body? (Remember TEVU)

• A->C->B

• A->C->G

• E->F->H

• D->F->G

Which statement describes a function of the human male reproductive system?

• It produces gametes in the testes

• It supplies a fluid that protects the fetus

• It provides support for the development of the embryo

• It provides nutrient materials through the placenta

An organism which reproduces asexually will have offspring

• The same genes as both of its parents

• Different genetic info as either of its parents

• Different genes from its parents

• With the same genes as its parents

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• mRNA

• Ribosome

• Nucleotide
