Answer 1

Here is the matching of terms from Column A to Column B:

1. allele: **b. alternate forms of a gene**
2. phenotype: **l. the appearance of a trait**
3. genotype: **d. the gene combination**
4. homozygous: **k. two alleles are the same**
5. heterozygous: **j. two alleles are different**
6. diploid: **c. contains 2 copies of each chromosome**
7. haploid: **h. contains 1 copy of each chromosome**
8. gametes: **f. sex cells**
9. dominant: **i. the trait that is always expressed**
10. recessive: **a. the trait that can be covered up**
11. independent assortment: **o. one of Mendel’s principles that states that genes for different traits can segregate independently during the formation of gametes**
12. segregation: **e. separation of alleles during gamete formation**
13. DNA fingerprinting: **m. a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA**
14. Nondisjunction: **p. one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division - resulting in nuclei and cells with the wrong number of chromosomes**
15. incomplete dominance: **g. type of inheritance with a third phenotype with a heterozygous genotype that is a blending of the traits (ie white x red = pink)**
16. codominance: **n. type of inheritance with a third phenotype with a heterozygous genotype, where both of the traits are expressed equally (ie type A x type B = type AB blood)**
