 Q1CQ2AQ3DExplanation:So, the cross between true breeding white corn plant and purple corn plant will have the genotypes kkpp(white) and KKPp(purple).The cross,P1      kkpp (white corn)         ×             KKPp (purple corn)             ↓                                                 ↓G1       kp                                             KP, Kp                                                ↓F1         kpkpKPKkPpPurple corn plantKkPpPurple corn plantKpKkppRed corn plantKkppRed corn plantSo the offsprings produced is 50% red corn and 50% purple plants.Q4DQ7AHeterozygous green parakeet has BbYy genotype - possible allele combinations passed down: BY, bY, By, byWhite parakeet has bbyy genotype - possible allele combinations passed down: byWhen put in a punnet square, total genotypes are: BbYy, bbYy, Bbyy, bbyyTheir phenotype colour, in the above order are: green, yellow, blue, white.So probability of yellow or blue is 2/4 or 50%. (Parent genotypes were listed above)Q13In both cases the chances of having a Lab Retriever with a black coat is 75%. To solve this question I have created a Punett square for the combination of GgBb x GgBB. Because there are two genes for each genotype there are 4 possible combinations that could result in the breeding of the individuals GgBb and GgBB. As you can see for the individual GgBb the possible combinations that could be passed on to their offspring are; GB, Gb, gB and gb. You know right away that any combination of genes with GB will result in offspring with a black coat because G means that there is no possibility of yellow offspring and B is the dominent gene for black.  see ATTCHEMENT Q14A Attached file Thumbnail(s): You must login or register to gain access to this attachment.
