Answer:
The answer is XX.
Explanation:
Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous to have the short phenotype which means it needs to have the genotype xx or Xx.
The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.
I hope this answer helps.
There are different types of channels for blood flow that transport the blood pumped by the heart. They greatly differ only in the size of their diameters. Arteries are the big ones that are located mostly near the heart. Veins are the next which is where nurses inject you to gather blood. Then, the smallest ones are the capillaries.
Answer: Interphase; Prophase; Metaphase; Anaphase; Telophase
Explanation:
1) The genetic material is duplicated (Interphase)
2) Chromosomes become visible the spindle apparatus forms (Prophase)
3) The chromosomes line up in the middle of the cell. (Metaphase)
4) The cell plate forms; the nuclear envelope is formed. (Anaphase)
5) Chromosomes move to opposite ends of the cell (Telophase)
