How would phenotype of monohybrid f1 and f2 showing incomplete dominance in snapdragon and co dominance in human blood group be different from mendelian monohybrid f1 and f2 progeny . Explain?
Answers
Answer:
A monohybrid cross is a mating between two organisms with different variations at one genetic chromosome of interest.[1][2] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. A cross between two parents possessing a pair of contrasting characters is known as monohybrid cross. To carry out such a cross, each parent is chosen to be homozygous or true breeding for a given trait (locus). When a cross satisfies the conditions for a monohybrid cross, it is usually detected by a characteristic distribution of second-generation (F2) offspring that is sometimes called the monohybrid ratio.
Figure 1: Inheritance pattern of dominant (red) and recessive (white) phenotypes when each parent (1) is homozygous for either the dominant or recessive trait. All members of the F1 generation are heterozygous and share the same dominant phenotype (2), while the F2 generation exhibits a 6:2 ratio of dominant to recessive phenotypes (3).
