Answer Stats
| Hint | First Letter | Answer | % Correct |
|---|---|---|---|
| The basic physical and functional unit of heredity. | G | Gene | 85%
|
| The common name of deoxyribonucleic acid, the molecule that carries genetic information for the development and functioning of an organism; made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. | D | DNA | 84%
|
| (of an allele) When the alleles of a gene are different, the allele that is expressed. | D | {Dominant} allele | 80%
|
| One of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. | A | Allele | 79%
|
| The common name of Ribonucleic Acid, a single-stranded organic molecule composed of nucleotides. | R | RNA | 79%
|
| A person who can pass an inherited (genetic) disease on to their children but who does not have the disease. | C | Carrier | 77%
|
| (of an allele) Having no tangible effect, or that is masked by the effects of a dominant allele. | R | Recessive | 75%
|
| The single cell formed by the union of gametes (sperm and egg); a fertilized egg. | Z | Zygote | 74%
|
| A threadlike structure made of protein and a single molecule of DNA that serves to carry the genomic information from cell to cell. | C | Chromosome | 68%
|
| The complete set of genetic information in an organism. | G | Genome | 68%
|
| Membrane-bound organelles that generate most of the chemical energy needed to power the cell’s biochemical reactions. | M | Mitochondria | 68%
|
| An individual's observable traits as determined by their genomic makeup and environmental factors. | P | Phenotype | 64%
|
| A specific characteristic of an individual, determined by genes, environmental factors or by a combination of both. | T | Trait | 62%
|
| Having inherited the same versions (alleles) of a genomic marker from each biological parent. | H | Homozygous | 53%
|
| Having inherited different versions (alleles) of a genomic marker from each biological parent. | H | Heterozygous | 52%
|
| A cell having two complete sets of chromosomes; one set is inherited from the mother, and one set from the father. | D | {Diploid} cell | 51%
|
| A type of mutation in which part of the DNA sequence is lost; the loss can be as small as a single base pair or as much as an entire section of a chromosome. | D | Deletion | 50%
|
| A specific, fixed position on a chromosome where a particular gene or genetic marker is located. | L | Locus | 50%
|
| Any chromosome that is not a sex chromosome. | A | Autosome | 47%
|
| The alleles or variants an individual carries in a particular gene or genetic location. | G | Genotype | 46%
|
| A type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual. | C | Co-dominance | 36%
|
| A mutation that causes the premature death of an organism, often in the early stages of embryonic or fetal development, but sometimes after birth. | L | {Lethal} mutation | 36%
|
| A gene that resides on the X chromosome. | X | {X-linked} gene | 26%
|
| A condition wherein the dominant allele completely masks the effect of the recessive allele. | C | Complete dominance | 25%
|
| A form of gene interaction in which both alleles of a gene at a locus are partially expressed. | I | Incomplete dominance | 25%
