Question
In a dihybrid cross involving two heterozygous parents
(AaBb × AaBb), what is the expected phenotypic ratio, assuming independent assortment and complete dominance?Solution
In a dihybrid cross (AaBb × AaBb), using Mendel’s law of independent assortment, the phenotypic ratio follows 9:3:3:1, where: 9 = dominant for both traits 3 = dominant for A, recessive for B 3 = recessive for A, dominant for B 1 = recessive for both traits
Statements: S * K, T $ K, K @ B
Conclusions:
a) S $ B
b) S @ B
Statements: X > O > D; T > M ≥ O; X > R
Conclusions:
I. T > R
II. R < DStatements: G@B; W#Z; B%W
Conclusions:
I) G@Z
II) Z@B
Which of the following symbols should replace (1) and (2) respectively in the given expression in order to make the expression N > P definitely true?
Statements:
J $ R % U % C
Conclusions:
I. R © C
II. J * U
III. C % J
Statements: T < Q ≥ L; W < Q ≥ E; E < S
Conclusions:
I. T < S
II. S > Q
III. E < L
- Statement: L = N ≥ O ≥ P > R = Q > S = T
Conclusions:
I. S < O
II. L ≥ Q
III. P > T Statements: R > S ≥ T = U < V ≤ W; X ≥ Y = Z < U = M ≥ N
Conclusions:
I. S ≥ M
II. T < X
III. W > N
