What is the result of this process?
an increase in offspring variation.
the deletion of amino acid sequences.
an increase in mutations in genetic material.
the production of gametes that are genetically identical.
Which statement describes crossing over as it occurs in meiosis?
The alleles of a gene separate.
Spindle fibers pull apart sister chromatids.
Genes move to opposite ends of the chromosome.
Homologous chromosomes exchange segments of DNA.
Which organism will pass mutations to their offspring?
L and M
L and O
N and M
N and O
Which statement describes evidence that supports your choice in the previous question?
Offpring genotypes are determined by gametes.
Offspring genotypes are determined by both somatic cells and gametes.
Independent assortment of alleles in somatic cells causes mutated genes to be passed on to offspring.
Mutations in somatic cells are highly inheritable because they transport nutrients throughout the organism.
Select two pairs of species that share the greatest genetic similarity based on the results of the gel electrophoresis.
C. parreyssi and C. gaillardoti
C. canopicus ans C. prasidens
C. prasidens and C. gaillardoti
C. parreyssi and C. prasidens
C. canopicus and C. aegyptiaca
A mutation occurs in the DNA base sequence GGG GAG TTA resulting in the base sequence GGA GAG TTA. Use the information in the table to determine the effects of this mutation on the amino acid chain produced.
Proline is now lysine and leucine is unchanged.
Proline is now lysine and asparagine is unchanged.
Proline is unchanged and asparagine is unchanged.
Proline is unchanged and leucine is now phenylalanine.
A scientist examines a fruit fly gene involved in the regulation of body development. A section of the DNA sequence for the gene is shown. Which amino acid sequence would be produced from this DNA?

How could genetic engineering be use to produce a more successful crop in a hot, dry climate?
Non-essential DNA could be removed from the genomes of the crop plants.
DNA from plants adapted to dry area could be added to the genomes of the crop plants.
RNA from a varity of nonagricultural plants could be added to the genomes of the crop plants.
mRNA transcripts of genes from dry weather crops could be added to the fertilizer used on the crop plants.
Which pair of species is the most closely related?
Species 4 and Species 5
Species 5 and Species 6
Species 2 and Species 4
Species 2 and Species 6
Scientists discover a new species of bacteria that has a similar genetic makeup as a previoulsy studied bacterial species. Which investigative tool should be used to genetically compare the new bacteria to the previously studied bacteria?
gene therapy
chi-squared test
gel electrophoresis
electron microscope
Some bacteria have developed a resistance to antibiotics through random mutations. One such mutation allows bacteria to produce enzymes that inactivate the antibiotics when they enter the bacteria. Which statement describes how this mutation occurs?
The mutation occurs when nucleic acids are replicated.
The mutation occurs in chloroplast during photosynthesis.
The mutation occurs in mitochondria during cellular respiration.
The mutation occurs when molecules move across the cell membrane.
Which molecule was coded for by the longest piece of DNA, assuming that no post-transcriptional RNAprocessing or splicing has occurred?
A protein with 25 amino acids.
a polysaccharide with 60 sugars.
an mRNA molecule with 20 codons.
a mRNA molecule with 45 nucleotides.

A. XB Xb
b. Xb Xb
XB Y
Xb Y
A student studying feather color inheritance in a certain species of chickens observes that the chickens have black (homozygous), blue (heterozygous), or white (homozygous) feathers. The student hypothesizes that this feather color trait follows the incomplete dominance pattern. Which data table would support the student's hypothesis?
Parent 1- Black Feathers
Parent 2- White Feathers
Offspring- Blue Feathers
Parent 1- White Feathers
Parent 2- Black Feathers
Offspring- Black Feathers
Parent 1- White Feathers
Parent 2- White Feathers
Offspring- Black Feathers
Parent 1- Blue Feathers
Parent 2- White Feathers
Offspring- Blue Feathers
