WebGenetic analysis at this level involves observation and explanation of phenotypic patterns both among the offspring of specified hybrid crosses and among naturally occurring families. 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.

Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1). ( 2 votes) Upvote.
