The ways in which plants reproduce asexually and the way in which these mechanisms help to disperse offsprings. Introduction: Reproduction is a way of maintaining the continuity of race. The reproduction can be asexual or sexual. The sexual reproduction involves the fusion of male and female gametes. In plants, the male gametes are produced by stamens and female gametes is produced by ovary. Higher animals cannot reproduce asexually but in plants, there are two ways of reproduction. They are asexual mode of reproduction and the sexual mode of reproduction.

They are asexual mode of reproduction and the sexual mode of reproduction.

Expert Solution & Answer

Explanation of Solution

In plants, asexual reproduction takes place by fragmentation, grafting, layering, budding, and some other processes like apomixes. Apomixis is a method in which there is formation of seeds without undergoing through the process of fertilization. They are also able to reproduce by vegetative reproduction a method of reproduction in which a plant grows in a horizontal manner and it forms roots in an upright position.

The sugar can be reproduced by the fragmentation. In this process, the part of the stem is germinated into the soil, which later on gives rise to whole new plant. The grafting involves the joining of the stock of one plant and scion of another plant. The Bryophyllum have buds on its leaves, which can give rise to new plant.

Conclusion

The two ways in which the plants reproduce asexually are by the method of apomixis and the other method is by vegetative reproduction.

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:
