A cross between two individuals that are heterozygous for eye and skin color would be an example of a _____ cross.
8090 [49]

A cross between individuals that are heter0zyg0us for two different traits is a dihybrid cross. <em>A cross between two individuals that are heterozygous for eye and skin color would be an example of a _</em>dihybrid<em>_ cross.</em>

----------------------

Dihybrid crosses involve individuals that expresses two different traits and are heter0zyg0us for each of them.

So let us imagine we are studing the characters eye color and skin color. Let us assume that both of them are coded by single diallelic genes.

For eye color there is

  • Dominant allele B that codes for brown eyes
  • Recessive allele b that codes for blue eyes

For skin color there is

  • Dominant allele A that codes for black skin
  • Recessive allele a that codes for white skin

So, an individual that is heter0zyg0us for both of them, is BbAa.

If this person crosses to another person with the same genotype, we are talking about a <u>dihybrid cross</u>, because two dibybrid individuals are involved.

                             Cross:    BbAa      x      BbAa

According to this information, we can aswer the question:

<em>When crossing two individuals that are heterozygous for eye and skin color we are referring to a</em><em> dihybrid cross.</em>
