<span>The cilia and flagella of eukaryotic cells are made up of specifically designed microtubules. Microtubules are part of the cytoskeleton and are nucleated. They play an vital role in several cellular processes and also play a part in maintaining a cell's structure.</span>
The best and most correct answer among the choices provided by the question is the third choice "neap"
Neap tides<span> occur twice a month when the sun and moon are at right angles to the Earth. When this is the case, their total gravitational pull on the Earth's water is weakened because it comes from two different directions.</span>
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer:
See explanation below
Explanation:
<em>Non-disjunction occur as a result of lack of separation of homologous chromosomes during meiosis. </em>
As a result, the gametes (the daughter cells formed) produced end up having extra or lesser chromosomes as compared to a normal gamete.
When a gamete with extra chromosome fertilizes a normal gamete, the resulting offspring will have an extra chromosome (trisomy condition).
On the other hand, when a gamete with one less chromosome than normal fertilizes a normal gamete, the resulting offspring will have one less chromosome than normal offspring (monosomy condition).
Assuming a chromosome with Aa gene undergoes non disjunction during meiosis, the resulting gametes either contain both A and a chromosome or contain no chromosome at all.
If Aa gamete is fertilized by a normal haploid sperm (a), the resulting zygote will have the genotype Aaa.
If a gamete with no chromosome at all fertilizes a normal haploid sperm, the resulting offspring will have the genotype a.
T- tall allele
t- dwarf allele
This cross needs to be between 2 plants with the same genotype, like Tt xTt
In this cross it would result in:
1/4 of the plants being tall homozygote- TT
2/4 of the plants being tall heterozygote- Tt
1/4 of the plants being dwarfs homozygote- tt
