Answer» 1 hairy : 1 smooth Explanation: •• if heterozygous condition produces hairy stem, it MEANS hairy stem is a dominant character. now, let it's genotype by "AA" •• if pure breeding plant produces smooth stem, it means it is a receive homozygous condition, infered from 2ND STATEMENT. now, let the genotype be "aa" •• now, cross these two and the result will be --> Aa * aa = Aa, Aa, aa, aa •• Hence, two Are smooth and two hairy.... so, answer is option 1 |
