Answer:
The correct answer is - sex and blood type.
Step-by-step explanation:
Different organisms have different traits some are passed from the parents and other traits are developed by environmental influences. The traits that are passed from parents to the offspring are determined by the genes they inherited from the parents. In humans, sex is determined by the genes that present on the chromosomes and make the chromosome X chromosome or Y chromosome. The presence of the Y chromosome determines maleness.
Similarly, the blood group is determined by the genes, there are three alleles of the ABO gene present on chromosome 9; A. B. and O each allele code for a different antigen which helps them categorizing in blood groups.
