1. Sitka spruce trees oan have different colored reproductive cones. The breeding trees with green cones can be

crossed with true breeding trees with red cones. If these trees followed a codominant pattern of inheritance,

what phenotype would you expect?

offspring with red cones

@ offspring with orange cones

offspring with green cones

offspring with red and green cones

    D. offspring with red and green cones.

Explanation:

Codominance is a form of inheritance in which the alleles of a pair of genes in a heterozygous are fully expressed. As a result the offspring phenotype is a combination of the parents' phenotype. Therefore, the trait is neither dominant nor recessive.

In the codominant inheritance, two different versions so called alleles of a gene are expressed and each allele produces a somewhat different protein. Here, both versions influence the genetic trait or determine the characteristics of the genetic condition.
