Hello

according to the principle of segregation,

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

According to the principle of segregation, gene pairs for a trait are split during the formation of gametes.

Explanation:

This segregation was first observed by Gregor Mendel. He used pea plants for studying genetics. He crossed the pea plants and he discovered that traits in the offspring are not like the parental plants. He understands that alleles encoding the traits of each parental plant are separated during the formation of reproductive cells. By this only Mendel observed the principle of segregation. During meiosis only segregation of gene takes place and that produces reproductive cells called gametes.
