17. (a) What is the genotypic ratio in incomplete domucomplete dominance? |
|
Answer» A cross of two F1 hybrids, heterozygous for a single trait that displays incomplete dominance is predicted to give a 1:2:1 ratio among both the genotypes and phenotypes of the offspring. 1/4 will have the dominant phenotype (tall, TT), 1/2 will have the intermediate phenotype (Tt) resembling the parents of this cross, and 1/4 will have the recessive phenotype (short, tt.) When incomplete dominance occurs, it is not necessary to do a test cross to identify the heterozygotes. |
