Inheritance

Question	Answer
Inheritance	How traits or characteristics are passed on from generation to generation.
Allele	A variation of the gene for a particular trait/characteristic
Gene	A section of DNA that codes for a protein
Phenotype	The observation characteristics of an organism, it's appearance. Eg. tall, short, round, etc. Remember to say percentage. Eg. 100% brown eyes or 75% long arms, 25% short arms.
Genotype	The set of genes in our DNA which is responsible for a particular trait. The genetic makeup of an individual. Eg. 100% Bb or 75% BB, 25% Bb.
Dominant Allele	The characteristic always seen in the offspring. It always overpowers the other allele. Eg. If B=brown eyes & b=blue eyes than B is dominant (capital letter) If someone had a genotype of Bb the person would have brown eyes but carry a recessive gene.
Recessive Allele	The characteristic masked by a dominant one. - Lower case letter - Has to have 2 recessive alleles to show (eg. bb = blue eyes but Bb = brown eyes)
Heterozygous	Having two different kinds of allele. (Eg. Bb, eE, Gg, Yy, etc.)
Homozygous	Having the same alleles for a particular characteristic. Eg. TT, bb, ee, GG, PP, etc.
Monohybrid Genetics	Looking at how 1 trait (characteristic) is passed on to the next generation. It always has a dominant and recessive gene.
