Answer:
Separation of sister chromatids and centromeres.
Explanation:
Once chromosomes align along equatorial plate during metaphase of mitosis, the next step of mitosis is separation of the sister chromatids and the centromeres. The separation of sister chromatids and the centromeres occurs during anaphase of mitosis. During this phase, spindle fibres which are produced from centrioles in the centrosome at two opposite poles of the cell, attach to the centromere region of the chromosomes and drag each sister chromatid of the chromosome apart towards opposite pole of the cell. This is how each opposite pole receives one chromatid from each chromosome. Later during telpophase of mitosis, cytokinesis occurs which produces two daughter cells with equal number of chromatids.
Answer:
Cool air forms denser clouds, and when the clouds from the side of the mountain with cool air try to go to the side of the mountain with warm air, the clouds warm up and dissipate.
Answer:
continental drift – the idea that Earth's continents move
Explanation:
Answer:
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
Explanation:
Given that:
The allele → R = Red beetles
The allele → B = Blue beetles
Since the gene color shows a codominant allele
The Red Beetle = RR
The blue beetles will be = BB
The heterozygous beetle will be = RB
∴
The punnet square showing the crossing of RB × RR is:
R B
R RR RB
R RR RB
The result shows that we have two red beetles and two heterozygous beetles.
Hence;
The genotypic frequency = 1:1
The phenotypic frequency = 1:1
