(a)

Summary Introduction

To distinguish:

Animals and other organisms.

Introduction:

Animals come under multicellular organisms having eukaryotic cells. They lack cell wall. They are heterotrophs, acquiring the carbon and energy source from the organic compounds built by other organisms.

(b)

Summary Introduction

To distinguish:

Vertebrates and invertebrates.

Introduction:

Vertebrates are the group of animals which acquires a backbone and spinal cord to support their body. Invertebrates are the group of animals which do not contains backbone.

(c)

Summary Introduction

To distinguish:

Protostomes and deuterostomes.

Introduction:

Protostomes and deuterostomes are used to classify the subkingdom Eumetazoa included in Animalia, on the basis of embryonic development of animals. In protostomes the blastopore develops the mouth, while in deuterostomes it develops the anus.

(d)

Summary Introduction

To distinguish:

Ectotherms and endotherms.

Introduction:

Ectotherm and endotherm in animal classification represents the thermal regulation by the animals. Ectotherms cannot maintain their body temperature as they lack internal mechanisms. Endotherms regulate their body temperature by generating heat from the metabolic activities takes place in them.

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:
