(A)

(B)

(C)

(D)

Answer 1

Hint: The occurrence and appearance of certain phenotypes of a particular gene and organism are represented by a Pedigree chart. It results in the presentation of the family information with an easily readable chart.

Complete answer:
The mating between the male and female is represented by connecting the circle with the square in between two horizontal lines joined together. The chart displays and analyses the data on the heredity of one and another behavioral trait. The relationships in Pedigree is shown by a series of lines. The horizontal line and vertical line leads to the offspring of the parents which are connected by these lines and the offspring are connected by a horizontal sibship line which is listed in the birth order from left to right. The offspring are connected by a triangle if the offspring are twins and the symbols will be crossed by a line if an offspring dies. A small triangle represents the offspring that is stillborn or is aborted by the parents. The generations are identified by the Roman numerals and the analysis of Pedigree is used by the principle of Mendelian inheritance which determines that rate having a dominant or recessive pattern of inheritance.

Additional information:
The Pedigree Chart is constructed after a family member which is affected by a genetic order which has been identified and the individual is known as the proband which is indicated by an arrow in a Pedigree chart. These changes occur yearly or monthly. The Pedigree charts are established to determine the probability of a child having a particular disorder or a condition. they are used to discover the genes in a question which is located by x, y, or an autosome chromosome which determines whether the trait is dominant or recessive.

So, the correct answer is 'mating'.

Note: The pedigree chart provides information about the presence and absence of a given trait which is tracked by a Pedigree chart of two or more generations of a family. Widow's peak hairline is one of the examples of a Pedigree chart.
