Plant And Animal Breeding Flashcards
Back cross
Cross between F1 hybrid organism with parental type to maintain characteristics of a new breed
Cross breeding
Breeding organisms of different genotype together
Genome sequencing
Procedure to produce the nucleotide sequence of an entire genome
Inbreeding
Crossing organisms of the same or similar genotype
Inbreeding depression
Accumulation of homozygous recessive alleles that loser biological fitness
Recessive
Allele that only shows in the phenotype when homozygous
Replicate
Repeat the experiment in an investigation
Self pollinating
Passing pollen within the flowers of a single individual
Test cross
Cross between an organism of an unknown genotype and a homozygous recessive organisms
True breeding
Homozygous
Accumulate
Build up or magnify
Annual weed
Weed plant that completes its life cycle in 1 years
Biological control
Method of controlling pests using natural predators parasites or diseases
Crop pest
Organisms that reduces the yield of crops
Cultural
Based on human behaviour and activities
Ecosystem
Interaction between communities and their habitats
Ethology
Observation and study of animal behaviour
Integrated pest management
Use of chemical biological or cultural methods to control pests
Perennial weed
Weed that persists in the community by continuing to grow year after year
Persistent
Can’t be broken down by enzymes
Selective
Applies to pesticides whose action is targeted to
Systemic
Affecting all tissues of an organisms body
Welfare of animals
Relating to activities designed to be humane to live stock while maximising their yield
