An organism is for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s , or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are .
Mendel’s law of governs which allele is expressed in an individual.

1. homozygous

2. phenotype

3. linked

4. dominance

5. (a) brown, (b) brown, (c) green, (d) brown, (e) blue

6. The law of segregation states that each organism obtains one allele for a given gene from each parent in the reproductive process.

7. Mendel conducted hybridization studies looking at how cross-breeding of pea plants led to offspring with various characteristics. He wanted to understand how traits were passed from parent plants to their offspring.
