BIOXII05: PRINCIPLES OF INHERITANCE AND VARIATION

342281 In a typical Mendelian cross which is a dihybrid cross, one parent is homozygous for both dominant traits and another parent is homozygous for both recessive traits. In the generation, both parental combinations and recombination appear. The phenotypic ratio of parental combinations to recombination is:

1 \(10: 6\)
2 \(12: 4\)
3 \(9: 7\)
4 \(15: 1\)

342282 A dihybrid test cross-yielding a result of \(1: 1\) : \(1: 1\) ratio is indicative of:

1 4 different types of generation dihybrids
2 4 different types of gametes produced by the parent
3 4 different types of gametes produced by the dihybrid
4 Homozygous condition of the dihybrid

342283 In the cross Aa Bb X Aa Bb, what proportion of gametes are homozygous for both the traits

1 \(2{\rm{/}}16\)
2 \({\rm{1/4}}\)
3 \({\rm{0/}}16\)
4 \({\rm{4/}}16\)
