Polygenic inheritance is determined by multiple located at different loci on different chromosomes.

Polygenic inheritance is determined by multiple Genes located at different loci on different chromosomes.

Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.

This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.

Explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
