Define reciprocal, replicate and test crosses (mono, di), homozygous and heterozygous alleles, dominant and recessive phenotype.

Expert Solution
Step 1
  • Genetics is the study of the genetic and diversity particularities, which are the core features of living organisms.
  • Gregor Mendel is the father of Genetics  who proposed three laws namely, Law of Independent Assortment, Law of Dominance, and Law of Segregation. 
  • Via experiments on pea plants with a variety of characteristics, these laws came into being.
  • Alleles are called gene variants that occur by mutation and exist at the same relative locations on homologous chromosomes.
  • Mendel studied gene inheritance with only two types of alleles, but it is normal for a natural population to experience more than two alleles for any given gene.
