Genetics Vocab 1

Genetics Vocab Words 1

Genotype the combination of alleles that are present that give us our gene: some are dominant some are recessive
Phenotype the physical traits SEEN that express the type of allele in the genotype
Heterozygous a genotype where there is one dominant allele and one recessive allele in the gene; the dominant allele will be seen in the phenotype
Homozygous Dominant a genotype where both alleles are dominant in the gene
Homozygous Recessive a genotype where both alleles are recessive in the gene
Gene the basic code for developing features that comes from two alleles on the paired chromosome
Chromosome a structure in the nucleus that transfers genetic information from the parent cell to the daughter cell in living organisms; the transfer of chromosomes takes place during reproduction
Allele variations of genes that determine traits in organisms; two corresponding alleles on two paired chromosomes constitutes a gene
DNA inhereted information that is stored
Dominant more inuential allele; will be seen in the phenotype if present in the genotype
Recessive less inuential allele; will only be seen in the phenotype if it is the ONLY allele type present
Punnett Square a process used to determine all of the possible genotypes for offspring of sexual reproduction
Meiosis the process by which the number of chromosomes is reduced by half to form sex cells that will pass chromosomes onto the offspring
