Genetics

3. refers to a cell that contains both sets of homologous chromosomes
4. Homologous chromosomes exchange portions of their chromatins during meiosis
6. When homologous chromosomes fail to separate during meiosis, this leads to genetic disorders
9. The genes of an organism for one specific trait, always expressed using 2 letters
10. RNA codons are decoded into amino acids, using a codon chart
12. Trait that always shows. Can hide a recessive trait.
14. The physical appearance of a trait in an organism, what it looks like
17. three nucleotides on RNA that code for a single amino acid
18. Cell duplicates it's DNA, Complementary strands
19. genetic information ,found inside the cell nucleus

1. Two alleles that are the same for a trait
2. Discrete version of the same gene
5. makes up DNA and RNA, backbone (phosphate and sugar); nitrogen base
7. Two different alleles for a trait
8. a pair of chromosomes, one from each parent, which carry genes for the same trait
11. Trait that can be hidden.
13. process of reduction division in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell
15. refers to a cell that contains only a single set of genes
16. DNA copied to complementary RNA strand
