Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A set of traits an organism receives from its parents
A
heredity
B
DNA
C
chromosome
D
allele
Explanation: 

Detailed explanation-1: -The set of genes that an offspring inherits from both parents, a combination of the genetic material of each, is called the organism’s genotype. The genotype is contrasted to the phenotype, which is the organism’s outward appearance and the developmental outcome of its genes.

Detailed explanation-2: -Heredity, which is also known as inheritance or biological inheritance, is the passing of traits from parents to their offspring.

Detailed explanation-3: -Inherited, as related to genetics, refers to a trait or variants encoded in DNA and passed from parent to offspring during reproduction. Inheritance is determined by the rules of Mendelian genetics.

Detailed explanation-4: -Each variation of a gene is called an allele (pronounced ‘AL-eel’). These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.

Detailed explanation-5: -A heritable trait is most simply an offspring’s trait that resembles the parents’ corresponding trait more than it resembles the same trait in a random individual in the population. Inheritance or heredity was a focus of systematic research before its inclusion as a key concept within evolutionary theory.
