A
Genes alone determine the characteristics or organisms
B
A combination of genes and the environment determine the characteristics of organisms.
C
organisms have the same characteristics as their parents
D
Environment alone determines the characteristics of organisms
Explanation: 

Detailed explanation-1: -The extent to which a characteristic – like height – can be explained by your genes, as opposed to the environment, is called heritability. For example, scientists have estimated that about 60 to 80 per cent of a person’s height is determined by their genes and 20 to 40 per cent is determined by their environment.

Detailed explanation-2: -Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Detailed explanation-3: -An organism’s characteristics are determined not only by genes but by and interaction of environmental factors and genes. The environment can play a role in a person who has genes that give them a propensity to get disease but creating favorable conditions for those genes to be expressed.
