Plants reproduce through the process of fertilisation. Fertilisation is the process where female and male cells join together to form an embryo inside the seed. The seed protects the embryo in preparation for germination when conditions permit the plant to produce new plants.

Seed plants are classified into two types to determine reproduction. First are the Angiosperms, this type of seed plant has flowers that have special structures for reproduction. Pollens are made by male cells, while ovules are made by female cells. Pollens are carried out through the process of pollination (e.g. wind blows, insects carrying pollen). Most angiosperms that don’t undergo pollination develop intro fruits. If it goes into pollination they become new flowering plants.

Second classification is the Gymnosperms, which are seed plants that are held in cones. Gymnosperms like Angiosperms also have male and female reproductive cells. Reproduction also occurs through pollination but most gymnosperms are trees. The best example of a gymnosperm are pine cones.  </span>

Describe three possible effects of genetic drift on populations and/or specific alleles.
vfiekz [6]

Answer:

Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.
