what is the biomolecule that stores an organism's hereditary information. Long

sequences of DNA create

build a protein. The protein(s) created will generate a
_for that organism.
Further, there are thousands of genes in most organisms, so they must be kept somewhere safe. Organisms store their genes on units called which are kept in the nucleus of the cell.
2. T/F: Different organisms have different numbers of chromosomes.
3. T/F: Each chromosome carries one allele for a gene.
4. T/F: Diploid organisms receive two copies of each chromosome, which means they have two alleles for every gene..

  1. The biomolecule that stores an organism's hereditary information is DNA (deoxyribonucleic acid). Long sequences of DNA create genes, which hold the instructions for the cell to build a protein. The protein(s) created will generate a trait for that organism. Further, there are thousands of genes in most organisms, so they must be kept somewhere safe. Organisms store their genes on units called chromosomes, which are kept in the nucleus of the cell.

  2. True: Different organisms have different numbers of chromosomes.

  3. False: Each chromosome carries two alleles for a gene (one from each parent).

  4. True: Diploid organisms receive two copies of each chromosome, which means they have two alleles for every gene.

  5. True: The alleles that organisms receive are either dominant or recessive.

  6. If you get two dominant alleles from your parents, you are homozygous.

  7. If you get one dominant allele and one recessive allele from your parents, you are heterozygous.

  8. If you get two recessive alleles from your parents, you are homozygous.

  9. If an organism has one dominant allele and one recessive allele for a trait, he/she would show the dominant trait.

  10. The only genotype that can show the recessive phenotype is homozygous recessive (i.e., having two recessive alleles, such as "aa").

  11. The law that states that alleles are assorted into reproductive cells (gametes) separately is Mendel's Law of Segregation. a. True: If you are Tt for a gene, you will either give T or t, but not both. b. False: If an organism has the genotype GG for one gene and Mm for another, he/she could not generate a gamete with "gM". The possible gametes from these two genes would be:

  • From GG: G (only one possible allele since both alleles are the same)
  • From Mm: M or m
  • Therefore, the possible gametes are: GM, Gm.
  1. The law that states that genes are given to organisms independently from one another is Mendel's Law of Independent Assortment. a. False: Having small hands does not necessarily mean that you must be less than 5'6".
