Question:

what are non-additive alleles?

according to my textbook an additive allele is when alleles have their effects add up to influence the phenotype such as height, hair curliness, skin color, etc. but i see no definition for non-additive, it may seem easy to assume that it‘s the opposite but I want to be sure I have the correct answer. Thank you!

Answer:

A form of allelic interaction in which there is no dominance. The heterozygote is intermediate in phenotype between homozygotes for the alternative alleles. For multiple-gene traits, approximately equal contributions made by many loci. This is basically what happens in continuous variation (quantitative variation such as height where many genes have an additive effect on the final phenotype).
Just brake completely in third when you do a complete stop. When you accelerate have it on first.
when you slow first roll off accelerator apply brake ( you don't have to apply hard) once your hand has squeezed the front brake the brake light will come on blip the throttle down shift apply more hand brake blip throttle change down apply hand brake you can also push on the rear brake to make the brake light stay on whilst your slowing down. this is a good use for the back brake pedal because the rear brakes wont slow you down much learn to use the front brake. in an emergency its all that's going to stop you
first cluch and then slowly break you needed
