Question

The transmission of traits from parents to offspring is called ____
A)Characteristic
B)Heredity
C)Donation
D)Both A and B

Answer 1

Hint: Like chromosomes, genes also are available in pairs. Each of the parents has copies of all of their genes, and every discern passes alongside simply one replica to make up the genes you have. Genes which might be handed directly to you decide a lot of your traits, together with your hair colouration and pores and skin colouration.

Complete answer:
Heritable traits are known to be transmitted from generation to generation through DNA, a molecule that encodes genetic information. DNA is a long polymer that contains four types of bases that are interchangeable. The sequence of nucleic acids (base sequences along a specific DNA molecule) determines the genetic information: this is equivalent to a sequence of letters outlining a text passage. Before the cell divides by mitosis, the DNA is replicated such that each of the resulting two cells inherits the DNA chain. A part of a DNA molecule that determines a particular functional unit is called a gene; different genes have different base sequences.

Within cells, the long strands of DNA shape condensed systems called chromosomes. Organisms inherit genetic cloth from their mother and father withinside the shape of homologous chromosomes, containing a completely unique aggregate of DNA sequences that code for genes. The unique vicinity of a DNA series inside a chromosome is referred to as a locus. If the DNA series at a selected locus varies among individuals, the distinctive types of this series are called alleles. DNA sequences can alternate through mutations, generating new alleles. If a mutation takes place inside a gene, the brand new allele can also additionally have an effect on the trait that the gene controls, changing the phenotype of the organism.

Hence, the correct answer is option (B)

Note: Maternal inheritance is a case where genes present in mitochondria always pass from mother. Fathers receive mitochondrial genes from their mothers but never pass them to their children.
