- Determine the F1 generation of a cross between
plants with the following genotypes: rrPp and RrPP.
- Create a Punnett square with the allelic combinations of rrPp on the x axis and RrPP on the y axis.
- Enter the possible combinations in the 16 blank, middle squares.
- Calculate the genotypic ratio for the F1 generation.
- Calculate the phenotype ratios for the F1 generation and record the phenotypic ratio.
I know this is more than one question and don't expect you to answer all of them. I just need help understanding how to set up my Punnett square. Any help would be greatly appreciated.
Homework Answers
rrPp * RrPP
the gametes produced by rrPp are rP and rp, and the gametes produced by RrPP are RP and rP.
A) and B)
the gametes produced by RrPP are entered in the Y axis ( left most row) and the gametes produced by rrPp are given in the X axis ( top most row)
the genotype of the offspring are given in the punnet square the genotype of the offspring is the combination of the genotypes of the gametes fused to form the zygote.
| rP | rP | rp | rp | |
| RP | RrPP | RrPP | RrPp | RrPp |
| RP | RrPP | RrPP | RrPp | RrPp |
| rP | rrPP | rrPP | rrPp | rrPp |
| rP | rrPP | rrPP | rrPp | rrPp |
the genotypes of the F1 generation is given in the punnet square.
C) the genotypic ratio
RrPP:rrPP:RrPp:rrPp=1:1:1:1
D) phenotype produced by each allele is not given so assuming R and P are dominant alleles and r and p are recessive alleles,
the phenotypic ratio is
2 (dominant phenotype for both loci):1 ( dominant phenotype at R loci) :1 (dominant phenotype at P loci).

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...

a) In radishes, the plants can be tall (allele T) or dwarf (allele t). Tall is dominant. Root color can be red (allele RR), white (allele RW), or pink (heterozygote). A radish that is true-breeding for both red roots and tallness (RRRR TT) is crossed with a radish that is true-breeding for both white roots and being dwarf (RWRW tt). Write the genotype and phenotype for the F1 generation. b) Assume the two genes for plant height and root color are...

15. You are studying com plants. You were able to determine that the gene for kernel color (C-colored and no color) and kernel waxiness (W = waxy and not waxy) are on the same chromosome and are 30 CM apart. You are ultimately interested in determining the potential phenotypic ratio if crossing over occurs. You start by crossing a male who is homozygous dominant for both genes with a female who is homozygous recessive for both genes. The F1 heterozygotes...

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,...
