B

Back cross to recessive

identification of the recessive carrier can be done by a test mating with a known homozygous recessive animal. This will determine if the other animal is carrying a recessive gene. If they are carrying a recessive gene, then a percentage of the animals show the recessive characteristic. If they are not a recessive carrier then the recessive characteristic will not appear. We will use the Labrador as an example at the end of the glossary.

Back scatter

scattered radiation which travels in the opposite direction to the primary beam
