The contrasting pairs of factors in Mendelian crosses are called:

Correct answer: B. Allelomorphs

  • A. Multiple Alleles
  • B. Allelomorphs
  • C. Alloloci
  • D. Paramorphs

Explanation

The correct option is b) Allelomorphs because it refers to the contrasting pairs of factors in Mendelian crosses. In Mendelian genetics, allelomorphs are alternative forms of a gene that occupy the same locus on homologous chromosomes and determine different expressions of a particular trait. They represent the different versions of a gene that give rise to different phenotypes, such as the dominant and recessive forms in a monohybrid cross.

About Inheritance

Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
