During metaphase 1 of meiosis of the cell cycle chromosomal translocation occur.
Explanation:
Chromosomal translocation is abnormal phenomenon when a fragment of chromosomes detaches and gets stick to the non-homologous chromosome in an individual. These are causative of aneuploid, cancer and infertility in organism.
In metaphase 1 of meiosis the chromosomes gets aligned on the metaphase plate. This leads to surety of equal number of chromosome in the cell.
Chromosomal translocation are seen in metaphase 1 because it is the phase of rearrangement of chromosomes where fragments easily gets attach to the other chromosome.

Answer:
Genotypic frequency (How often the allele combination shows YY, Yy or yy)
YY - 490/1000 = 0.49
Yy - 420/1000 = 0.42
yy - 90/1000 = 0.09
Allelic frequency (How often the allele shows Y or y)
P = Frequency of Y = (490+420)/1000 = 0.91
q = Frequency of Y =(420+90)/1000 = 0.51
The population isn't in equilibrium according to Hardy-Weinberg because p + q is more than one.
Hardy-Weinberg equation is p+q =1
P^2 +2pq + q^2 = 1
The Hardy-Weinberg assumption the population violated is that there is gene flow as seen in the Allelic frequency that is more than 1
Explanation:
When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations.
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
Answer:
The fossil record
Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones.
Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.
Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.
Answer:
yes
Explanation:
Pretty much is only with breathing. If a person has asthma, the inside of these airways is irritated and swollen. Asthma can cause shortness of breath, wheezing, coughing, and tightness in the chest. For some people, asthma symptoms only appear when they are exposed to something that irritates their breathing. Others have a kind of asthma that makes breathing difficult all of the time.
