B11 inheritance Flashcards
mitosis
as nuclear division giving rise to genetically identical cells (details of stages are not required)
genotype
as the genetic make-up of an organism in terms of the alleles present
phenotype
as the observable features of an organism
heterozygous
as having two different alleles of a particular gene
homozygous
as having two identical alleles of a particular gene
dominant
as an allele that is expressed if it is present
recessive
as an allele that is only expressed when there is no dominant allele of the gene present
mutation
as a change in a gene or chromosome
evolution
as the change in adaptive features of a population over time as the result of natural selection
process of adaptation
as the process, resulting from natural selection, by which populations become more suited to their environment over many generations
inheritance
as the transmission of genetic information from generation to generation
chromosome
as a thread-like structure of DNA, carrying genetic information in the form of genes
haploid nucleus
as a nucleus containing a single set of unpaired chromosomes, e.g. in gametes
diploid nucleus
as a nucleus containing two sets of chromosomes, e.g. in body cells
gene
as a length of DNA that codes for a protein
