Homework Answers
1.
| A | a | |
| A | AA | Aa |
| a | Aa | aa |
AA is homozygous dominant and 1 out of 4 offspring pair is AA and the answer is
1 out of four (1:4) or 25 %
2.
| G | g | |
| G | GG | gg |
| g | Gg | gg |
Genotype of yellow pea plant is gg and 2 out of 4 progeny has gg genotype
Hence the answer is 2 out of 4 (2:4) or 50 %
Please rate the answer positively if you find it useful

I’m so confused by this, please explain Punnett Squares Reginald Punnett was a British geneticist who developed the Punnett square to explain how the chromosomes of parents cross and produce offspring. In order to solve genetics problems using a Punnett square, it is necessary to a) understand the associated vocabulary and b) understand some of the rules for solving the problems. · Before you continue with the problems below, review the meaning of the terms allele, dominant, recessive, homozygous, heterozygous,...

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...
