Sexual imprinting is when an animal learns to distinguish what an appropriate mate looks like to avoid inbreeding. Associative learning is any learning process in which a new response becomes associated with a particular stimulus. The most fa...

Alternate forms of a gene are called _______. a. alleles b. chromosomes c. gametes d. a phenotype - ANS Alleles Describing a person as having hemophilias is to indicate his or her ______. a. genotype b. phenotype c. genetic code d. number of chromosomes - ANS Phenotype Why do your chromosomes come in pairs? a. Because DNA is double-stranded, one member of each chromosome pair carries a strand that is complementary to the strand carried by...

Insulin is a protein that is produced by pancreatic cells and secreted into the bloodstream. a. Since all the cells in a person's body contain the same DNA, why do only our pancreatic cells produce insulin? b. If we insert the human gene for insulin into bacteria, the bacteria will produce human insulin. How is this possible? - ANS a. Our pancreatic cells only produce insulin, but because the DNA is the same, certain genes in cells can be turned "on" or "off" to fulf...

Alternate forms of a gene are called_______. - ANS alleles Describing a person as having hemophilia is to indicate his or her ______. - ANS phenotype Why do your chromosomes come in pairs? - ANS Because one member of each pair came from my mother and the other from my father.

(Ch. 16) - ANS Pyrimidine, Purine A DNA double helix is formed through the interactions of which part of a nucleotide? (Ch. 16) - ANS Nitrogenous base Every cell in your body contains ____...

Insulin is a protein that is produced by pancreatic cells and secreted into the bloodstream. Since all the cells in a person's body contain the same DNA, why do only our pancreatic cells produce insulin? - ANS Because some of our cells can be turned on or off to fulfill certain functions If we insert the human gene for insulin into bacteria, the bacteria will produce human insulin. How is this possible? - ANS Because bacteria can reproduce asexually, cells can code and deco...

How many chromosomes do human body cells have? - ANS 46 A somatic cell that contains two matched sets of chromosomes has a configuration known as _____________? - ANS Diploid what type of configuration do gametes have? - ANS Haploid During ______________, the cell grows and DNA is replicated. - ANS Interphase What results from mitosis? - ANS 2 daughter cells each diploid (2n) This Phase of mitosis: The centrosomes begin to move to opposite p...

Johann Gregor Mendel - ANS Father of setting the framework for the study of genetics through his experiments with 30,000 pea plants. What is a true breeding pea plant? - ANS where a flower's petals reain tightly sealed until pollination to prevent the pollination of other plants. Hybridizations, what is it, and who performed them? - ANS Mendel performed them, this involves mating 2 true breeding individuals that had different traits. How did Mendel have the pe...
