To meet the needs of local educators regarding K-12 biology education by providing professional development activities, opportunities to exchange ideas, and appropriate resources for elementary, middle, and high school. We seek to encourage learning in the life sciences that is inquiry-based, applicable to real-world happenings, and consistent with the Kentucky Core Content.
*Not all classes will go until 9:10 p.m.
Interesting hypothesis but not quite right, why?
A Some of these changes make no difference to the organism, whereas others can change cells and organisms. Only mutations in germ cells have the potential to create the variation that changes an organism’s future offspring.pair of homologous chromosomes,
each in the unduplicated state (most often, one from a male parent and its partner from a female parent)
Gene – unit of DNA information about a trait
Alleles – different versions of a gene
Nature selects which variations are best for survival and reproduction;
‘survival of the fittest’
