Smooth pods are dominant over constricted pods. If one parent has constricted pods and the other parent is homozygous for smooth pods, select all of the following that are true of the offspring. all of the offspring will have smooth pods 100% of the offspring will homozygous recessive all of the offspring will have constricted pods 75% of the offspring will have constricted pods and 25% will have smooth pods 100% of the offspring will be heterozygous 50% of the offspring will have constricted pods and 50% will have smooth pods 100% of the offspring will be homozygous dominant

Reed · Answer 1

If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.

The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.

If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:

P: AA x aa

F1: Aa Aa Aa Aa all of the offspring are constricted

Another combination:

P: Aa x aa

F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.

So, the correct answers are:

• all of the offspring will have constricted pods

• 50% of the offspring will have constricted pods and 50% will have smooth pods.
