| Question | Answer |
|---|---|
| Genetics | the study of heredity |
| Heredity | the transfer of characteristics from parent to offspring |
| Alleles | different factors passed from parent to offspring |
| Chromosomes | threadlike structure of DNA and protein that contains genetic information |
| Dominant | allele expressed/exhibit when present |
| Recessive | allele expressed/exhibit when dominant not present(or homozygous) |
| Homozygous | organism that have two identical alleles for the same gene |
| Heterozygous | organism that have two different alleles for the same gene |
| Genotype | genetic make up of an organism |
| Phenotype | physical characteristics of an organism |
| Gametes | sex cells |
| Fertilization | the joining of a haploid sperm and a haploid egg to form a diploid zygote |
| Zygote | a fertilized egg |
| Hybrids | the offspring of "crosses" between parents with different traits |
| Give an example of a homozygous | tt (short) |
| Give an example of a heterozygous | Tt (tall) |
| Give an example of phenotype | blue eyes, green eyes, brown hair, black hair...etc. |
| What are Gametes? | it is an egg or sperm |
| How is a dominant allele shown? | capital letter |
| How is a recessive allele shown? | lowercase letter |
| Founder of genetics? | Gregor Mendel |
| Which combination of alleles will the recessive trait be seen? | tt |
| Which combination of alleles will the dominant trait be seen? | TT or Tt |
| Give a Homozygous recessive | tt |
| Give a Heterozygous dominant | Tt |
