GENETICS Please Help! The answers have been provided under the question but I really need to see the work/explanation is done as I do not understand. Thank you very much!!

A) For the child of mother (a), the father could be:   
1 or 4

B) For the child of mother (b), the father could be:   
Answer: 1 or 3

C) For the child of mother (c), the father could be:   
Answer: 5

D) For the child of mother (d), the father could be:   
Answer: 2

E) For the child of mother (e), the father could be:   
Answer: 1 or 3 or 4

(a) (c) (d) (e) Maternal Phenotype A MR B Nr OMr ANR AB MINr Child Phenotype OMR ONr A MNR AB MNR A MN r Genotype of Male 2. PiMN RR. 3. iiNNrr 4. iiMMrr 5. AIAMNRR

Solution

A) For the child of mother with phenotype AMR, the father genotype could be:   I^Ai MNrr and ii MMrr.

B) For the child of mother (b), the father could be: I^Ai MNrr and iiNNrr.

Here mother’s phenotype is BNr and must have the genotype I^B iNNrr and when married with the person carrying the gene either I^Ai MNrr or iiNNrr will have child with ONr phenotype

C) For the child A MN R of mother OMr (c), the father could be:   I^AI^AMNRR

Because the mother has the genotype iiMMrr and the father has I^AI^AMNRR genotype and they may have the child with A MN R phenotype with either I^AI^AMNRr or I^Ai MMRr genotype.

D) For the child of mother (d), the father could be: genotype I^B iMNRR

Maternal phenotype ABMNR with genotype I^A I^B MNRR or I^A I^B MNRr and paternal genotypeI^B iMNRR may have , child with phenotype ANR with genotype either I^Ai NNRR or I^Ai NNRr.

E) For the child of mother (e), the father could be:   I^Ai MNrr , iiNNrr, iiMMrr
Child’s Phenotype=A MN r

Child’s genotype=: :   I^A I^A MNrr or I^Ai MNrr

Mother’s phenotype-AB MN r

Mother’s genotype= I^A I^BMN rr , So the father with genotype I^Ai MNrr or iiNNrr or iiMMrr may produce A MN r phenotype offspring.
