Question | Answer |
Genetics | study of heredity |
"Father of Genetics" | Gregor Mendel |
self-pollinating | they don't need another flower to reproduce |
Cross-pollination | taking pollen from flower and fertilizing a different flower with the pollen |
true-breeding | offspring only displays one form of a trait ex: all flowers are white and only make other white flowers when bred |
P generation | parent generation |
F1 generation | first filial generation |
F2 generation | *second filial generation |
Dominant traits | trait that remains seen (expressed) in F1 generation |
Recessive traits | trait that is not seen (not expressed) in F1 generation |
homozygous | Same information on the genes (ex: GG) |
heterozygous | Different info (ex: Rr) |
allele | Each copy of a gene |
Genotype | the set of alleles that an individual has (letters) |
Phenotype | how a trait looks when expressed (is the Physical appearance/how it looks) |
homozygous dominant | has 2 dominant alleles EX: TT |
homozygous recessive | has 2 recessive alleles EX: tt |
heterozygous | has 2 different alleles EX: Tt |
Probability | the chance or likelihood that a certain event will occur |
pedigree | Tracking traits in families by making a chart or family tree |
sex-linked trait | trait that is carried on only one of the sex chromosomes only (ex: hemophilia/color blindness |
cross | Represents the combining of male and female sex cells in Punnett squares. (When parents produce offspring.) |
heredity | The passing of traits from one generation to the next by means of genes. |
hybrid | An organism with one dominant and one recessive gene for the same trait. |
inheritance | Passing of traits from parents to offspring.. |
Punnett square | A genetic tool to solve genetics problems mathematically. |
trait | A distinguishing characteristic based on your genes (such as eye color or hair color). |
cross | Represents the combining of male and female sex cells in punnett squares. |
hybrid | A genotype with 1 dominant and 1 recessive gene (like Tt or Bb) |
pure | A genotype with 2 dominant or 2 recessive genes (like BB or bb or HH or hh |
The process where reproductive (sex) cells are formed: | Meiosis |
Process where body cells are produced | Mitosis |
An abnormal condition that a person inherits through genes or chromosomes | Genetic Disorder |
A person who has one recessive allele for a trait but does not have the trait | Carrier |
Two parent's child or creation | Offspring |
A segment of DNA that controls a trait | Gene |
