  19. 18 Life History Patterns • Biologists study the factor that determines population growth—an organism’s reproductive pattern, also called its ???

  20. Limiting factors, such as availability of food, disease, predators, or lack of space, will cause population growth to slow. • Under these pressures, the population may stabilize in an S-shaped growth curve. • The number of organisms of one species that an environment can support indefinitely is its ??? carrying capacity 19

  42. Spindle 41 • A) Cell structures composed of microtubules; forms between the centrioles during prophase and shorten during anaphase, pulling apart sister chromatids. • B)

  43. Telophase 42 • A) Final phase of mitosis during which new cells prepare for their own independent existence. • B)

  44. Gene 43 • A) Segment of DNA that controls the protein production and the cell cycle. • B)

  45. 44 • Incomplete Dominance • appearance of a 3rd phenotype. • Example: A homozygous red-flowered plant (RR) is crossed with a homozygous white-flowered plant (R’R’), all of the F1 generation offspring will have PINK flowers (RR’). R R R’ R’

  46. 45 • Codominance • Expression of both alleles • Example: Black (BB) rooster crossed with a white (WW) hen = checkered (BW) black and white. (Incomplete dominance would have been gray!)

  47. 46 • Traits controlled by more than 2 alleles have this… • multiple alleles • Example: Pigeons have 3 alleles that control feather color. • BA = ash red • B = blue • b = chocolate

  48. 47 • The 23rd pair of chromosomes in humans are ___ ____________and determine the sex of the offspring. XX = female XY = male sex chromosomes
