Running water both beach answers and valleys
The offspring will inherit one allele from each parent.
<h3><u>Explanation</u>:</h3>
The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.
One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.
The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.
Now as they are crossed the offsprings will have genetic combination of Yy.
This is seen that the offsprings carry one allele from both the parents.

a the adaptation that made possible the colonization of dry land environments
by seed plants is most likely the result of the evolution of pollen.</span>
The main advantage of seed plants
(Gymnosperms and Angiosperms) is the evolution of the seed which, unlike
spore-producing plants, was not limited to wet environments. Pollen grains are
male gametophytes (sperm) which are protected from desiccation and can reach
the female organs without dependence on water. The sperm is transferred from
the pollen through the pollen tube: an extension of a cell within the pollen
grain. The process is called pollination.

Answer:
12 chromosomes
Explanation:
Mitosis is a type of cell division that involves the formation of two genetically identical daughter cells. The two daughter cells are genetically identical in the sense that they contain the same number of chromosomes as the parent cell. Mitosis involves four stages namely: Prophase, Metaphase, Anaphase and Telophase.
In the metaphase stage as stated in this question, homologous chromosomes align at the equator of the cell called cell plate, before each chromatids are pulled apart by microtubules at the Anaphase stage.
According to the question, the spider being worked on has 6 pairs of chromosomes, which will align at the cell's equator during metaphase stage of mitosis. Since the replicated chromosomes (chromatids) are yet to separate to opposite poles of the cell, the cell will still contain 12 chromosomes at the metaphase stage.
N.B: Each chromosome contains 2 chromatids or replicated chromosome, which will be separated at the Anaphase stage. Each chromatid will be an individual chromosome after cytokinesis.
