<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
Answer:
Some practices from the recommended list of physical/cultural control that you could do year-round to help control pests are as follow:
1. We can use those plant species that are more competitive. These plant species include release of chemical toxins that suppress other plants and insects.
2. Use of large Hight quality seeds.
3. By using narrow spacing in row and increasing seeding rate.
4. By using shallow seeding technique which allow desired plant species to grow and develop faster above the surface of soil.
5. By ensuring that our plant species is perfectly placed in that growing environment which is optimized with every specs.
6. By rotating the crops
7. By rotating plant species with different growing cycles and seasonal cycles.
8. By rotating herbicides with alternative modes of action to delay the herbicide resistance development.
B) Bb x Bb because to have blue eyes they need to get the trait from both parents
For this, you need to use Punnett squares.
You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.
AABBCc divided like ABC and ABc.
Aabbcc divided like Abc and abc.
Now you can cross them, and all probabilities will be:
AABbCc, AaBbCc, AABbcc and AaBbcc
So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc
Answer:
Yes, viruses are super small. It is also smaller than bacteria. So you wouldn't notice anything.
