A monohybrid cross follows a single trait through one mating. Each parent contributes one of its two alleles at random to each offspring — this is Mendel’s Law of Segregation.
Cross two heterozygotes (Cc × Cc) and the offspring alleles combine in four equally likely ways.
Check yourself
Crossing Cc × Cc, what fraction of offspring show the recessive cream coat?
