non-sex chromosomes, in humans there are 22 pairs of these

both alleles of a gene contribute independently to the phenotype is ​ (a)  

• co-dominant trait
• holandric trait
• incomplete dominance
• epistasis

Match the following

• Mendel's Law of Segregation

• Alleles for a trait separate from one another during the formation of gametes

• Mendel's Law of Dominance

• genes found on different chromosomes are sorted into sex cells independently of one another during meiosis

• Mendel's Law of Independent Assortment

• in a heterozygote, one allele will conceal the presence of another allele for the same characteristic
