What happens in meiosis 1 when homologous chromosomes fail to disjunction? What happens to the cell after metaphase when the chromosomes meet in the middle? What happens to sepals, petals, and stamens after fertilization? What happens to the corpus luteum if fertilization does not occur? What is...
What is the difference between growth and development in plants? (a) What are the three degrees of dominance? (b) What happens in each? (a) What is a plasmid vector? (b) What is its significance? What is regeneration? What is the role of Agrobacterium tumefaciens in the production of ...
This second generation with triploid offspring is where the magic happens. Now these same techniques are being used on cannabis plants. So far the results are promising, but not yet widely studied or validated. This has the potential to be the biggest new technique in cannabis breeding since ...
Nondisjunction in Meiosis: Nondisjunction occurswhen homologous chromosomes or sister chromatids fail to separate during meiosis, resulting in an abnormal chromosome number. What is the role of Nondisjunction? Nondisjunction occurswhen chromosomes fail to segregate during meiosis; when this happens, gametes ...
Most women accepting prenatal testing are doing so not because they expect to have a positive result for a genetic condition. Instead, they rightly expect they are in the vast majority of women who are not carrying a child with a genetic condition. They are seeking reassurance. But, according...
Who described sexual reproduction in plants? Do plants only use sexual reproduction? What are the names of plants which reproduce sexually? How do humans utilize plant reproduction? What are the two main modes of reproduction in animals and plants? Explain how fertilization happens in fish...
What happens to the tube nucleus after pollination? What is the difference between germination, pollination and fertilization in flowers? How are plants in the family Asteraceae pollinated? How does the structure of the stigma aid in pollination?
What hormone is detected for a pregnancy test? Where does it come from? Describe what happens during each month of fetal development. What are the three stages of childbirth? Describe each of them. How does copper affect fertilization?
How did speciation in Darwin's finches occur? What is genetic convergent evolution? How does sympatric speciation occur in animals? What is adaptive divergence in evolution? What happens in divergent evolution? How are convergent evolution and evolution by common descent different?
