Answer:
The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.
It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.
Answer:E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
Explanation:
Chargaff's rules state that in a given DNA molecule the percentage of Adenine %A is approximately equals the percentage of Thymine %T and the percentage of Guanine %G is approximately equals the percentage of Cytosine %C.
Answer is
E. coli: Cytosine- 26, Thymine-24
Human: Guanine-20, Cytosine-20
Ox: Guanine-21, Cytosine-21, Thymine-29
Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
