monohybrid inheritance Flashcards
inheritance
transfer of genetic information from generation to generation
genotype
genetic makeup of organism
phenotype
observable feautures of organism
homozygous
having 2 identical alleles of a particular gene
heterozygous
having 2 different alleles of a particular gene
dominant
allele that’s expressed if present
recessive
allele that is expressed only if there’s no dominant
test crosses are used to
identify unknown genotypes
codominance
where two different alleles of a specific gene are simultaneously expressed
blood group alleles
dominant: A and B
recessive: O
sex-linked characteristics
feature in which the responsible gene is located on a sex chromosome making it more common in one sex
example of sex-linked characteristic
red-green colour-blindness
