It has to be confirmed through scientific tests in a lab.
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: C. cropping patterns
Explanation:
Cropping pattern can be defined as the area in which the different crops grow at different times of the year. It also consider the spatial arrangement and time used to grow a sequence of crops that are grown in a particular area of land.
The given situation is indicative of the cropping patterns as different crops are grown in the same land over particular period of the year.
Answer: Option C
Explanation:
Color blindness is a common hereditary condition which means it usually passes from parents. Red green color blindness is passed on from the mother to the son.
The chromosome number 23 is the sex chromosome also responsible for colorblindness. As it is sex linked the son can receive the recessive allele from the mother.
The mother of the child had a recessive allele which she transferred into her son. As it is sex inherited disease the son is affected by gene carried from mother.
