Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.
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:
Flow of Energy can be explained by means of two models namely: single channel energy model and Y-shaped energy model.
