Genetic inheritance definitions

• Gamete is a reproductive sex cell with 23 chromosomes
• Chromosome is made up of strands of DNA
• Gene is a section of DNA that codes for a protein and leads to a trait
• Allele are different forms of a gene, humans have 2 for each inherited gene
• Dominant allele - allele that is always expressed even when 1 copy is present
• Recessive allele - only expressed if there are 2 copies (bb)
• Heterozygous is when an inherited allele is dominant and the other is recessive
• Homozygous is when both alleles are equal, either 2 dominant or 2 recessive
• Genotype is the combination of alleles, for example, Bb
• Phenotype refers to physical characteristics
• Incomplete dominance is when the phenotype produced by heterozygotes falls between that of the two homozygous parents.
• What is this called?
