Answer:
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
Explanation:
- A (colored seed) is dominant over a (colorless)
- Wx (normal starch) is dominant over wx (waxy)
Both loci are independent.
A <em>Aa WxWx </em>individual was test crossed (crossed with a homozygous recessive <em>aa wxwx</em> individual).
- The homozygous recessive can only produce <em>a wx </em>gametes.
- The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 <em>A Wx </em>and 1/2<em> a Wx </em>
<u>The possible offspring resulting from the combination of those gametes is:</u>
- 1/2 Aa Wx wx (colored seeds, normal starch)
- 1/2 aa Wx wx (colorless seed, normal starch).
Answer:
The problem needs to be stated at the beginning of the process.
Explanation:
Conclusions are formed at the end.
It is VERY important to form a hypothesis.
And data can be analyzed many many ways.
That would be B - Metabolism.
Answer:
3. Separation of sister chromatids
Explanation:
Before entering mitosis or meiosis, DNA contained in a cell duplicates and and each chromosome will have two sister chromatids.
- In mitosis the sister chromatids separate to produce two daughter cells that have the same information as the original cell before the DNA duplicated.
- On the other hand, meiosis consists of two cell divisions. During meiosis I, homologous chromosomes separate, producing two daughter cells that have half the information the original cell had, but each chromosome still has two sister chromatids. During meiosis II, the sister chromatids separate, and each daughter cell produces two more daughter cells, that now have a single homologous chromosome of the pair, and which has a single chromatid.
