Founder of genetics
Gregor Mandel is the founder of genetics, he did this by doing experiments with pea plants. He found that genes are aquired from both parents and that traits have dominant and recessive alleles.
pattern where phenotype of both homozygote parents are produced in heterozygous offspring so that both alleles are equally expressed EX: TT + tt = Tt
Inheritance pattern where the phenotype of a heterozygote is intermediate between those of the two homozygotes; neither allele of the pair is dominate but combine to make a new traitEX: A yellow and blue phenotype mix to make a green phenotype
Presence of more then two alleles for a genetic traitEX: BBa
These are traits that are controlled by genes located on the sex chromosomes. An example of this is the red eye, white eye traits in houseflys. The eye color trait was located on the X chromosomes but not the Y chromosomes
