QUESTION 1 Axial flowers (A) are dominant to terminal flowers (a) and Mendelian.

Question

QUESTION 1 Axial flowers (A) are dominant to terminal flowers (a) and Mendelian. On average, a monohybrid cross of AA plants crossed to aa plants in the P generation would lead to a genotype ratio in the F2 generation of b.3 AA: 1 aa C. 1 AA:2Aa:1aa O d- all Aa O e. QUESTION 2 In a Mendelian monohybrid cross, the plants of the F1 generation a are all homozygous dominant. b. all have the dominant phenotype. ??. care 75% dominant phenotype and 25% recessive phenotype. d. are all homozygous recessive. e, are 50% homozygous and 50% heterozygous.

Explanation / Answer

1. c. 1AA : 2Aa : 1aa

AA x aa

F1 - Aa

Aa x Aa

Punnett square analysis:

So the genotype of the F2 generation is: 1AA : 2Aa : 1aa

2. b. all have the dominant phenotype.

In Mendelian monohybrid cross between two true breeding organisms, the F1 generation gives the phenotype of the dominant organism.

A a A AA Aa a Aa aa
