Traits can be influenced by:
by both paternal DNA and maternal DNA
only paternal DNA
only maternal DNA
only maternal grandparent DNA
by both paternal DNA and maternal DNA
Human traits and characteristics are determined by genetic material inherited from both parents. Specifically, offspring receive 50% of their nuclear DNA from the mother (maternal DNA via the egg cell) and 50% from the father (paternal DNA via the sperm cell), both of which interact to influence the phenotype.

Just like baking a cake using ingredients supplied equally by two different chefs, an offspring's traits are a blend of genetic instructions coming from both mother and father.
MOM plus DAD = DNA mix
Total┬аchromosomes=46 тАФ diploid number in human somatic cells
Gamete┬аchromosomes=23 тАФ haploid number in sperm and egg
During fertilization, a haploid sperm cell fuses with a haploid egg cell to form a diploid zygote containing 46 chromosomes (23 pairs). Each pair consists of one chromosome from the mother and one from the father. The genes on these homologous chromosomes undergo expression, dominance, and recessiveness interactions, contributing to the organism's inherited traits.
Offspring receive equal amounts of nuclear DNA from both parents.
Maternal mitochondrial DNA is inherited exclusively from the mother, but general physical traits are shaped by nuclear DNA from both parents.
Genes exist in pairs called alleles, with one allele inherited from the mother and the other from the father.
Genetic diversity through recombination and sexual reproduction
Adaptability and resilience against environmental changes
Genetics and hereditary studies
Forensic DNA profiling and paternity testing
Option A is correct because both parents contribute half of the nuclear genetic makeup.
Options B and C are incorrect because relying on only one parent's DNA would ignore the principles of bisexual reproduction.
A is correct тАФ traits can be influenced by both paternal DNA and maternal DNA.
Remember that while mitochondrial DNA comes exclusively from the mother, overall inherited traits and nuclear genetics involve equal contributions from both parents.
