Genetics Flashcards
Incomplete Dominance
Neither allele is dominant or recessive with respect to each other. Both alleles work in the heterozygous genotype to produce an intermediate phenotype
Natural Selection
The process by which those organisms with genetically controlled characteristics, that allow them to be well adapted to their environment, will survive and reproduce to pass on their genes to the next generation
Gene/Point Mutations
Changes in a single gene
Mutagens
Agents that cause mutations
Progeny
The offspring produced
Locus
It’s position on a chromosome
Mitosis
The cell divides to produce two daughter cells with the same number of chromosomes as the parent cell
Fertilisation
The union of two gametes to form a single cell called a zygote
Chromosome Mutations
Large changes in the structures or number of one or more chromosome
Mutation
A change in the structure or amount of DNA
Genetic Engineering
The artificial manipulation or alteration of genes
Meiosis
The cell divides to produce 4 daughter cells with half the number of chromosomes as the parent cell
Homozygous
The two alleles are the same
Heterozygous
The alleles are different
Dominant
The allele prevents the recessive allele from working
