The pedigree chart below shows the individuals in a family who exhibit a certain trait. Based on the information in the chart, what twoconclusions can be drawn? (Both conclusions need to be selected.) (2 points) A diagram of a pedigree chart. At the top of the chart are two individuals: one indicated by a green circle and one by a green square. At the next level down, the green circle is paired with a black square and the green square is paired with a black circle. From the green circle/black square pairing, there are three offspring: a green circle, a green square, and a black square. From the green square/black circle pairing, there are eight offspring: three black circles and four black squares. Two of the black squares are identical twins. One of the black circles is paired with another black square. This pairing produced one green circle.

Hello there!
Attached is the diagram you have described. Here are the choices for your question:
A. It is a recessive trait.
B.It is a dominant trait.
C.Individual 12 is homozygous for the trait.
D.Individual 12 is heterozygous for the trait.
The answers are:
A. It is a recessive trait.
The trait is not dominant because if the trait was dominant, one of the parents (III-4 or III-5) should show the trait (meaning, should be color green). But both parents don't show the trait so the trait must be recessive.
D. Individual 12 is heterozygous for the trait.
Individual II-3 has genotype aa and individual II-4 is most probably AA. This will result to all their offsprings to be heterozygous Aa.
I hope this will help you!

D
