Codominance a. involves the expression of both alleles at a locus producing two different phenotypes.
b. is only found in mammalian enzyme production.
c. would result in pink flowers from a cross between white and red flowers.
d. involves one allele having more than one phenotypic effect.
e. occurs when heterozygotes show a phenotype intermediate between those of the two homozygotes.

A. involves the expression of both alleles at a locus producing two different phenotypes.

Explanation:

Codominance is the expression of both alleles, and is the result of a heterozygous expression. Let's say a white and red flower produce offspring, if the offspring come out with white with red spots, then it will be codominant. Both of the colors are present in the offspring, without mixing. Incomplete dominance is the mixing of the colors, so if the offspring came out as pink, it would be incomplete dominance.  

d

step-by-step explanation:

an inequality is an expression which means more than one number is a solution. we graph the solutions on a number line to show all possible values. we graph using circles and arrows.

this is a filled in circle on -2 so this is . this means only answers c and d are options.

answer d points to the right.
