Mendel + Genetics Flashcards
homologous chromosomes
paired chromosomes with genes for the same traits arranged in the same order
dominant
visible, masks recessive, capital letter
phenotype
organisms physical/outward appearance
genotype
organisms gene combination
homozygous
identical alleles for a trait (tt or TT)
heterozygous
nonidentical alleles for a trait (Tt)
genetics
branch of biology that studies heredity
mendel
austrian scientists (also monk) who was first to succeed in predicting how traits are transferred throughout generations
dihybrid cross
two organisms, two traits
zygote
fertilized egg that transforms into an organism by mitosis
genetic recombination
genetic variation resulting from crossing over
crossing-over
process that happens in prophase I which results in genetic variation
punnet square
way of finding the possible genotypes in an offspring
monohybrid cross
two organisms, one trait
