Eаch persоn inherits twо cоpies of аny given gene from their pаrents. Those who inherit two copies of the same gene variants (variants are called alleles) are known as homozygous individuals (the prefix “homo-” means “the same”). Those who inherit two different alleles of the gene are known as heterozygous individuals (the prefix “hetero- “means “different”). Whether an individual is homo- or heterozygous is their “zygosity.” Determine and record the zygosity of samples 1, 2, and 3, from the simulation, in the table below. DNA Sample 1 DNA Sample 2 DNA Sample 3 Zygosity (homo/hetero) [DNA1] [DNA2] [DNA3] Allele (s) contained (TNF1 and/or TNF2) [DNA4] [DNA5] [DNA6]
