Term
| Pre-conception paternal influence |
|
Definition
| The father's experiences can affect the genetic material that is inherited in offpsring through many methods to be described |
|
|
Term
|
Definition
inheritance of phenotypes because it is thought to show some underlying fitness and is hence sought after by mating partner... it is thought of as "handsome"
Phsycial charcteristics can indicate things such as social status, acess to resources, parenting skills and good genes |

Term
|
Definition
| Sexual selection is carried out by mate choice. There are specific factors that have been noted to contribute to mate selection of animals. For example diversity in immune system genes is often a determinant of mate selection. Also genetic similarity (breeding avoidance) can be detected and contributes to mate selection. |
|
|
Term
| Major Histocompatability Complex |
|
Definition
| MHC... component of the immune system... is a way to recognize the self from foreign. Allows body to recognize fooreign proteins and create antibodies to those proteins. diversity in the number of these genes will tanslate into more likeliness that they will bea ble to launch an immune response. |

Term
|
Definition
| Series of phenotypic and behavioral characteristics that result from embryonic exposure to alcohol. |
|
|
Term
| Paternal Alcohol Intake Effects |
|
Definition
| Produce some characteristics similar to FAS, including in rodents hyperactivity and poor impulse control. Reduces the number of appropriate enzymes in different tissues including enzymes that methylate in sperm therefore effects could be due to a decrease in methylation. There is also lower body weight in male offspring. |

Term
|
Definition
| Process through which mRNA is produced from a DNA template |
|
|
Term
|
Definition
| Process through which amino acid strand is produced from mRNA strand |
|
|
Term
|
Definition
| Any change to DNA sequence, can be caused by environmental factors such as radiation/toxins |
|
|
Term
|
Definition
| Changes in the structure of DNA/associated proteins that alters the way that the DNA is transcribed, yet does not change the sequence itself |
|
|
Term
|
Definition
| Addition of a methyl group to Cystine. It blocks the appropriate enzymes from transcribe the genetic sequence, hence silencing it. |
