Robertsonian translocation

The long arms of two acrocentric chromosomes become joined to a common centromere through a translocation, generating a metacentric chromosome with two long arms and another chromosome with two very short arms. The smaller chromosome is often lost because very small chromosomes do not have enough mass to segregate properly during mitosis and meiosis.

Monohybrid Crosses Reveal

F1 plants display the phenotype of only one parent, they must inherit genetic factors from both parents.

When dominant and recessive alleles are present together, the recessive allele is masked, or suppressed.
