According to the principle of segregation,

a.)gene pairs for a trait are combined during fertilization
b.)gene pairs for a trait are split during the formation of gametes
c.)dominant genes will always mask recessive genes
d.)traits are determined by heritable factors called genes and genes

The principles that govern heredity were discovered by a monk named Gregor Mendel in the 1860s. One of these principles, now called Mendel's Law of Segregation, states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. ... Organisms inherit two alleles for each trait.

gene pairs for a trait are split during the formation of gametes

Explanation:

"The combination of two genes determines the genetic trait of an organism. Mendel hypothesized that during the formation of gametes, the pair of genes controlling a trait separated. Thus, each gamete carried only one gene for the trait from each pair. The process of gene separation during gamete formation is referred to as the principle of segregation."
