EOC Ecology Test

If one parent is Homozygous Dominant (AA) and the other is Heterozygous (Aa) for a trait, what is the probability that their child will be Heterozygous for that trait?

• 50%

• 25%

• 75%

• 100%

Which of the following are examples of a Heterozygous Allele?

• AA

• Aa

• aa

True or false: the genotype refers to the letters and its what codes for the physical characteristics you see which is the phenotype

• True

• False

Which genetic phenomenon results in offspring with a phenotype that is a blend of the parents' phenotypes?

• Incomplete Dominance, because the offspring's phenotype is a mix of both parents' traits

• Codominance, because the offspring displays both parents' phenotypes equally

• Complete Dominance, because one parent's phenotype completely masks the other's

• Mitochondrial Inheritance, because the phenotype is inherited from the mitochondria

What are the genotypes of the offspring's?

• AA, Aa, AA, Aa

• AA, AA, AA, aa

• aa, aa, AA, AA

• AA, AA, Aa, Aa

You have to look at cells under the microscope because they cannot be seen with the naked eye. Is this statement true or false?

• True

• False

What structure is responsible for photosynthesis in plant cells?

• Nucleus

• Golgi apparatus

• Chloroplast

• Lysosome

What process is primarily responsible for growth and repair in multicellular organisms by duplicating its DNA and dividing?

• Meiosis leading to genetic diversity

• Mitosis resulting in identical cells

• Binary fission in prokaryotic cells

• Cytokinesis as a standalone process

What kind of cell is this picture showing?

• Plant cell

• Animal Cell

• Mitosis Cell

• Meiosis Cell

In a HYPERTONIC solution, water LEAVES the cell and the cell shrinks (gets smaller).

• True

• False
