Matching Pairs HeredityOnline version Life Science by Melodie Gonzalez [STUDENT] 1 The process by which scientists modify the genome of an organism. 2 Genes that are expressed when homozygous genotypes are present. 3 Used to determine the probability of outcomes of offspring. 4 Determined by whether or not a dominant trait is present. 5 The trait that is expressed. 6 Because a person has more genes than expressed, there are many different possible combinations of genes their offspring can have. 7 Genes that are expressed when a heterozygous genotype is present. 8 The characteristics we get genetically from our parents and our relatives before them. 9 Any of the forms of a specific gene that can be present on the same location of a chromosome. 10 A person with both a dominant and recessive alleles. 11 The study of heredity, or how certain features pass parents to their offspring Genetics Genetic Engineering Gene Expression Punnet Square Dominant Traits Phenotype Alleles Variation Of Traits Heredity Heterozygous Recessive Traits
