Answer:
q = 0.2, p = 0.8
Explanation:
According to Hardy-Weinberg equilibrium,
p + q = 1
p² + 2pq + q² = 1 where,
p = frequency of dominant allele
q = frequency of recessive allele
p² = frequency of homozygous dominant genotype
2pq = frequency of heterozygous genotype
q² = frequency of homozygous recessive genotype
Here,
q² = aa = 0.04
q = √0.04 = 0.2
p = 1 - q
= 1 - 0.2
= 0.8
The process of naming and grouping organisms is known as taxonomy. This naming system was started by Carolus Linnaeus. The system groups plants and animals by relationships and characteristics. Each organism is given a Latin name.
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
Answer:
Binary Fission: cell division in prokaryotes; Mitosis/Cytokinesis: cell division in eukaryotes, required to sort multiple linear chromosomes; Both: asexual reproduction, parent cell gives rise to two daughter cells, DNA is copied before process starts, daughter cells are clones of each other, daughter cells are identical to parent cell
Explanation:
Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
