Answer:
a) Genotype ratio= 1/2 Gg: 1/2 gg
Phenotype ratio = 1/2 yellow seeds: 1/2 green seeds
b) Genotype ratio= 1/4 GG : 1/2 Gg: 1/4 gg
Phenotype ratio= 3/4 yellow seeds : 1/4 green seeds
Explanation:
a) Genotype of heterozygote parent plant = Gg
Genotype of homozygous recessive parent plant= gg
A cross between Gg x gg gives progeny in following ratio= 1/2 Gg (yellow seeds) : 1/2 gg (green seeds)
b) Parent plants = GG x gg
F1= Gg
A cross between Gg x Gg would give F2 progeny in following ratio= 1/4 GG (yellow seeds): 1/2 Gg (yellow seeds) : 1/4 (green seeds)

Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

Answer: A) Layers 1 and 2.
Explanation:
Secondary succession refers to when species of plants and animals come back to recolonise an area that was destroyed by a natural disaster of some sort or human activity that change the makeup of the area but somehow left it still capable of supporting life.
As the species that come during secondary succession come after the land has been destroyed so to speak, they would be the later species to arrive which would mean that when they died they would be the closest to the surface when their body decays.
Secondary succession would therefore most likely be observed between layers 1 and 2.
