Question

The sex of an infant is not a case of inheritance of characteristics
A. True
B. False

Answer 1

Hint: The process of how an offspring receives genetic information from the parent is called inheritance. Inheritance of characteristics refers to the transmission of characteristics from the parents to their offsprings.

Complete answer: Inheritance of characteristics involves the inheritance of genes by the offspring from their parents. The heredity is dependent upon the inheritance of traits or characters from the parents. Hence, this is the reason for the offspring’s being similar to the parents. Sex determination is used to determine the sex of an infant. A biological system in which the development of sexual characteristics in an organism can be determined is called sex- determination. Offsprings are produced by sexual reproduction with each organism having two sets of chromosomes. Sexual morphology can be specified as males and females have different alleles or even different genes. XO, ZO, XY, XZ, chromosomes, or haplodiploidy are the different combination of chromosomes which help in the determination of sex. Inheritance of characteristics was first discovered by Gregor John Mendel. Gregor John Mendel derived the principles of Mendelian inheritance by performing experiments using the Pisum Sativum plant. Therefore, the above-given statement is true.
So, option A is the correct answer.

Note: Gregor Mendel proposed three laws of inheritance after successfully conducting the experiments. The law of dominance states that an organism with at least one dominant allele will have the phenotype appearance of the dominant allele. The Law of segregation states that the alleles for each gene segregate from each other during gamete formation. Each gamete carries only one allele for each gene Law of independent assortment states that during the formation of gametes Genes of different traits can segregate independently.
