heterozygous round and yellow seeded pea plants were selfed and total 800 seeds are collected. what is the total no. of seeds with first dominant and second recessive traits?
1) 950
2) 300
3) 200
4) 150

 

In Mendel's dihybrid cross, the first dominant and second recessive trait will be with Round and green seeds.

Since 800 seeds were collected, in accordance with the dihybrid 9:3:3:1 ratio, there will be 150 seeds with first dominant and second recessive trait.

acc or to 9:3:3:1 ratio 3 out of 16 are round green which are first dominant and second recessive.Therefore 16-3 800-? x=800×3÷16=150 ans =150 seeds

Answer is 150 seeds...save this pic in your gallary to see this solution clearly
