Trait 1: Simple dominant recessive inheritance
Example: In pea plants, Y and Yy genotypes will yield yellow pea pods, but inherited yy will yield green pea pods.
Trait 2: Co-dominance
Co-dominance occurs when there's more than one dominant allele and they express equally.
Example: Human blood type is co-dominant. IA (type A blood), 1 (type B), and i (O blood) are controlled by A and B
dominant alleles. If a person inherits A and B alleles, they'll have AB blood. O blood is caused by two recessive
alleles.
Trait 3: Incomplete dominance
Incomplete dominance occurs when there is more than one dominant gene, but the expression of both genes
creates a blending of traits.
Example: RR = red flowers, WW = white flower, but RW = pink flowers.
Come up with your three traits and the possible inherited phenotypes. Here's an example:
Trait
Phenotype 1
Phenotype 2 Phenotype 3 Phenotype 4
Yy and YY
(simple/dominant recessive) (yellow seeds)
yy (green seeds)
Flower Color
(co-dominance)
18 and is red flowers Wand IW - white flowers WR = red/white speckled li =yellow flowers
Pod Shape
(incomplete dominance)
PP = long balloon-shaped pods FF = flat, narrow pods PF = long flat pods
To get started, think about the traits your species needs to help it survive in its environment. Come up with
variations of these traits. You can include neutral traits (variations that won't affect the organism's survival), and
beneficial traits (variations that would give the organism a better chance for survival). You can even include
harmful genes or genes that could cause genetic diseases. Fill in the chart with the traits you chose and the
possible inherited phenotypes.

Calvin ate a candy bar, which caused his body's blood glucose levels to become unbalanced. his body responded by initiating a feedback mechanism to return his body to homeostasis. place the steps of this feedback mechanism in order, starting with the blood glucose imbalance that occurred after calvin consumed the candy bar. a) calvin's blood glucose levels decreased. b) calvin's pancreas stopped secreting insulin. c) calvin's body cells started to take up glucose and store it as glycogen. d) calvin's blood glucose levels increased. e) calvin's pancreas started secreting insulin.
