alleles- different forms of genes.
dominant gene- when 2 gametes fuse, each with a different allele for the same gene, the dominant trait is demonstrated (BB, Bb, bB).
genes- chemical factors that determine traits.
-found in locus (loci)
genotype- the genes you have.
Gregor Mendel- good at math, keen observer, good questioner
~P generation- parent generation
~F1- 1st offspring
~F2- cross of F1 offspring
heterozygous- 1 dominant and one recessive allele
homozygous dominant- 2 dominant alleles for a trait
homozygous recessive- 2 alleles of the recessive genes
hybrid- the mix of a dominant and recessive allele
phenotype- your physical characteristics (traits)
recessive gene- a gene that is phenotypically expressed in the homozygous state, but has its expression masked in the presence of a dominant gene (bb).
Hopefully while reading this blog you will find the notes that you need. Maybe you missed them because you were sick, lazy, or just did not see the point of having them at the time. Well no matter what the reason is, here they are, or at least some of them. If you have a chance check the main site for more subjects. Feel free to comment on the posts as well.
