<span>Stem cells are like the stem of a plant cell because they both can help replace or fix something

Answer:
You didn't put a description, maybe if you do i can answer it
Explanation:
He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !
Answer:
The parent with the genotype Aa BB Cc dd can produce 4 different types of gametes.
Explanation:
<em>The law of independent assortment states that the alleles for a trait separate when gametes are formed. </em>
In the parent genotype Aa BB Cc dd, the allelic pairs with variation present are Aa and Cc. Therefore, the source of variation in the possible combinations during meiosis, largely arises from these 2 allelic pairs.
Independently assorting these pairs, we have ; A, a, B, B, C, c, d, d
The possible combinations therefore are:
The cell cycle is divided into the following five stages:
1. Interphase: The cell increase in size. The cell synthesize a complete copy of DNA in its nucleus.
2. Prophase: Chromosomes condense and are more visible. The nuclear membrane disappears. Centrioles separated at move to the opposite poles of the cell. Spindle fibers forms and radiate towards the center of the cell.
3. Metaphase: Chromosomes line up across the middle of the cell. Spindle fibres connect the centromere of each sister chromatid to the cell poles.
4. Anaphase: The centromere that join the sister chromatid split. Sister chromatids separate becoming individual chromosomes and moving to the opposite poles of the cell.
5. Telophase: Chromosomes uncoil. A nuclear envelope forms around each chromosome. Spindle fiber breaks down and dissolves.<span />
