The correct answer is: C) shortening of microtubules
Chromosome movement is possible thanks to changes in microtubule length. Several types of microtubules are involved. First, during the anaphase kinetochore microtubules shorten and consequently the chromosomes move toward the spindle poles. Then the astral microtubules that are anchored to the cell membrane pull the poles further apart. At the end of anaphase, the interpolar microtubules slide past each other and that additionaly separate the chromosomes.
Answer:
Huntington's disease is caused by an inherited defect in a single gene, meaning yes it is likely. more likely will get symptoms between the ages of 30-40s
Answer:
Explanation:
Lets Tan seed be TT
Red seed be tt
A cross between TT ×tt will produce 4 Tt
TT× tt
!
F1 Tt Tt Tt Tt
a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.
A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.
The genotype of the F1 melon is Tt in a dominant form
The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1
72Tan seeds:24red seeds
Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.
Tt ×Tt
!
F2 TT Tt Tt tt
Phenotypic ratio 3:1
Answer:
b.option is some how correct.
Explanation:
D, it is only dominant because it stands out more not because it is better
