Chapter 3, Problem 25P

a.

Summary Introduction

To determine: The different genotypes that can be seen in the grid of 16 squares.

Introduction: Mendel discovered most commonly two types of crosses based on the number of characters studied at a time. The cross can be monohybrid, dihybrid.

b.

Summary Introduction

To determine: The phenotype of the genotype obtained in the given cross.

Introduction: The given genotypic ratio of the cross 9:3:3:1 is obtained when a plant with two characters are crossed and are studied at a same time.

c.

Summary Introduction

To determine: The formula that can depict the number of genotype in the given cross.

Introduction: The different crosses, whether monohybrid, dihybrid or any other cross will result in the different number of genotypes which represent the different combinations of genes.

d.

Summary Introduction

To determine: The different genotypes that will represent the similar phenotype.

Introduction: The genotype represents the genetic composition which further depicts the phenotype of that individual.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
