which statement is true about DNA?

• DNA is made up of genes that carry hereditary information

• different people can have the same copy of DNA in their cells

• DNA controls the genotypes but not the phenotype

• DNA only controls genotype in second and third generations

what relationship exists between genes and chromosomes?

• genes produce chromosomes which transmit traits from one generation to another

• genes are made up of chromosomes which move from the nucleus to the cytoplasm

• genes are located on chromosomes which are found in the nucleus of cells

• genes and chromosomes produce alleles which determine the phenotype of offspring

which statement describes why eye color is an inherited trait?

• it depends on the color of light entering the eye

• it is passed from the parents to the offspring

• it depends on the amount of vitamin A

• it changes as a child grows to become an adult

which statement summarizes the relationship between chromosomes DNA and genes?

• genes change the DNA located on some chromosomes

• genes are sections of DNA located on chromosomes

• dna makes up the chromosomes located on genes

• chromosomes make up the genes located on DNA

which statement accurately describes how genetic information is transferred during meiosis?
