In a certain mammal erect ears are dominant over drooping ears. In a cross between the 2 types, out of the offspring produced in the F2 generation 3 had erect ears and one had drooping ears. What were the genotypes of the parents. Work out the cross.
what the line "dominance is not an autonomous feature of a gene " means?????????????
what genetics principles could be derived from a monohybrid cross ?
what is meant by rudimentary ovaries?
Let us assume in a given plant the genotype symbol "Y" stands for dominant yellow seed colour and "y" for recessive green seeds colour symbol "R" for round seed shape and "r" for wrinkled seeds. Two homozygous parents (plants) with genotypes "RRYY" and "rryy" are crossed and their F1 generation progeny is then selfed. What shall be the
a) Phenotype of F1 progeny
b) Genotype of F1 progeny
c) Gemete genotype of F1 progeny
d) Phenotypic ratio of F2 population
e) Phenotypic ratio of yellow seed to green and round seed to wrinkled seed in F2 population.
