Uint 8.2 - monohybrid inheritance

what are genes

sequences of DNA that codes for a protein/characteristic

what are alleles

different forms of the same gene that can produce variations of the same protein or characteristic

what is monohybrid inheritance

the inheritance of characteristics controlled by a single gene

what is the combinations of genes called

genotype

what is a genotype

describes the genetic make-up of an individual

what is the phenotype

the outward appearance of an individual

what is a dominant allele

a form of a gene that is expressed in the phenotype

what is a recessive allele

form of a gene that is not expressed in the phenotype unless that individual holds 2 recessive alleles for that gene

what is homozygous

when you inherit the same DNA sequence for a specific gene from each of your biological parents (BB or bb)

what is heterozygous

when you inherit two different versions of the same gene (Bb)

when are test crosses used

when breeders want to find out if a plant with a dominant phenotype is homozygous or heterozygous
