5 True/False Questions

1. sex linkage → A situation in which both alleles in a heterozygous organism express themselves

   True        False

2. homozygous organism → has the same alleles at a locus, and a gene. Produces gametes that all carry the same allele

   True        False

3. The law of dominance → Whne an organism has two different alleles for a trait, the allele that is expressed and overshadows the expression of the other allele is said to be dominant; the allele whose expression is overshadowed is said to be recessive

   True        False

4. Homologous chromosomes → has the same alleles at a locus, and a gene. Produces gametes that all carry the same allele

   True        False

5. nitrogen cycle → The processes and pathways involved in capturing inorganic carbon-containing molecules, converting them into organic molecules that are used by organisms, and the ultimate release of inorganic carbon molecules back to the abiotic environment

   True        False
