Which of the following crosses best illustrates Mendel's First Law?
a. Homozygous cross
b. dihybrid cross
c. testcross
d. monohybrid cross
The correct option is d.monohybrid cross.
Mendel's first law is also known as the law of segregation. The law of segregation is the condition that, 'the alleles of a given locus segregate into separate gametes.' Alleles sort independently because the gene is located on a specific chromosome.
Mendel formulated the law of segregation as a result of performing monohybrid crossexperiments on plants.A monohybrid cross involves one character and different (hybrid) traits.The specific traits which were being studied exhibited complete dominance.In complete dominance, one phenotype is dominant and the other one is recessive.
