In flowering plants the gametophyte phases are reduced to a few cells dependant for their nutrition on the Sporophyte. The gametophyte comprises the main plant, while the diploid sporophyte is much smaller and is attached to the gametophyte. Both spores and the resulting ganetophyte are haploid, which means they only have one set of chromosomes. The mature gametophyte produces male or female gametes by mitosis. The fusion of male and female gametes produces a diploid zygote which then develops into a new sporophyte.
<h2>Genetics and Archaeology of Maize</h2>
Explanation:
- Genetic evidence pointed the archaeologists to a specific locality to look for evidence of maize domestication; archaeologists found microfossils on grinding stones that matched that age of the earliest maize predicted by DNA analysis
- Scientists used the archaeological and genetics evidence for discovering the origin of maize with the examination of DNA data
- Archaeologists examine the fossil evidences of maize in caves and determined the domestication of maize
- Hence, the right statement of discipline work is "Genetics Used DNA data pointed the likely location of the earliest maize"
Answer:
The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.
