WebIf a pure line pea plant with colored flowers (genotype = CCPP) is crossed to pure line, homozygous recessive plant with white flowers, the F 1 plant will have colored flowers and a CcPp genotype. The normal ratio from selfing dihybrid is 9:3:3:1, but epistatic interactions of the C and P genes will give a modified 9:7 ratio. WebMonohybrid Crosses. A monohybrid cross is one in which both parents are heterozygous (or a hybrid) for a single (mono) trait. The trait might be petal color in pea plants. When conducting crosses, the first generation is called P (or P 0 ), the second generation is F 1 (F is for filial), and the next generation is F 2.

If … Web11 feb. 2024 · Every plant will have two copies of each gene. We call this combination of alleles the plant’s genotype. The seed color we can observe is called the phenotype. Since seed color in pea plants is determined entirely by genetics (in fact, determined entirely by one gene!), you can actually perfectly predict the phenotype from the genotype. This ...
