Two plants with an inated seed shape produced 340ospring. Of those 340, six ospring had a constricted pod shape. What are the genotypes of the parents?

The genotype of both parents will be heterozygous for the trait, Ii.

Explanation:

Let us assume that the shape of the seeds is controlled by a single diallelic gene.

The individual with constricted seeds must have two recessive alleles i in its genotype ⇒ ii.

One of the i alleles was inherited from one of the parental plants, while the other parental plant provided the other i allele. So both parental plants must carry the recessive allele in their genotype.

We know that both parental plants have inflated seeds, which is the dominant phenotype.  

So, if both parental plants have inflated seeds and also carry the recessive allele, then the parentals´ genotype must be heterozygous, Ii.

Both plants exhibit the dominant inflated phenotype but carry a recessive allele which will be provided to some of the descendants. These last individuals will have constricted seeds.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
