Question

In maize plants, the allele M, for white seeds is dominant over the allele m for yellow seeds.100 heterozygous plants were self pollinated and 250 yellow seeds were collected. (a) What is the expected ratio of white seeds to yellow seeds (b) What is the expected total number of seeds (c) What is the expected number of white seeds

Answer 1

Answer:

(a) 250 (b) 750 (c) 1000

in monohybrid cross the ratio of dominant : recessive is 3:1

so here yellow which is the recessive charater has value 250

so the number number of white coloured seeds with ratio 3 will be 750

and the total number of seeds equal to white +yellow = 750 + 250 = 1000
