Sitka spruce trees can have different colored reproductive cones. true-breeding trees with green cones can
crossed with true-breeding trees with red cones. if these trees followed a codominant pattern of innenances
what phenotype would you expect?
a offspring with red cones
© offspring with orange cones
® offspring with green cones
offspring with red and green cones

The correct answer is : offspring with red and green cones.

Explanation:

Co-dominance follows non-Mendelian inheritance pattern. This is often caused due to the effect of multiple alleles of a particular gene, that get expressed simultaneously.Here, unlike in Mendelian form of inheritance pattern or incomplete dominance pattern where the effect of one allele of a gene is shadowed or blended by the other allele, both the alleles of the gene gets equally expressed in a heterozygous offspring.Therefore, the heterozygous offspring show the phenotype (both red and green cones) of both the true-breeding homozygous parents (each producing red and green cones, respectively).
