Use these symbols for the two different alleles upper band

Use these symbols for the two different alleles: upper band = D9BrapaSI^*2 lower band = D9BrapaSl^*2 Keep in mind that each of the individuals contains two alleles for this genetic marker. Determine the genotype of the: Maternal egg donor Child/Offspring Alleged pollen donor #1 Alleged pollen donor #2 Of the Child\'s alleles, which came from the egg?. Of the Child\'s alleles, which came from the pollen, whichever the pollen is?. Based on the above, can you exclude alleged pollen donor #1? Why or why not? Based on the above, can you exclude alleged pollen donor #2? Why or why not?

Solution

Maternal egg donor:D9BrapaS1*²

Child/offspring:D9BrapaS1*² and D9BrapaS1*¹

Alleged pollen donor #1:D9BrapaS1*¹

Alleged pollen donor #2:D9BrapaS1*²

D9BrapaS1*² this allele came from the egg.donor

D9BrapaS1*¹ this allele came from the pollen donor #1.

based on the above image we can take pollen donor #1 is the donor of D9BrapaS1*¹ allele, because these band is matched exactly with the child band.

based on the above image we can take pollen donor #2 is not the donor of D9BrapaS1*² allele because this band is matching with the egg donor allele.

final conclusion is pollen donor #1 and egg donor are the parents for the child or offspring
