The F1 genotype is At and Am since each of the two parents contribute their alleles.
The genotype of the F2 genotype is shown in the Punnet square below-
| F1 genotype | At | Am |
| At |
F2 genotype is: AtAt |
F2 genotype is: AtAm |
| Am |
F2 genotype is: AmAt |
F2 genotype is: AmAm |
According to the Punnet square given above, when is a cross is made between the F1 generation (AtAm x AtAm), the genotype of the F2 generation obtained will be-
AtAt, AtAm, AmAt, AmAm.

46. (7 points) Vanessa has obtained two true-breeding strains of
mice, each homozygous for an
independently discovered recessive mutation that prevents the
formation of hair on the body.
One of the mutant strains is called naked, and the other mutation
strain is called hairless. To
determine whether the two mutations are simply alleles for the same
gene, Vanessa crosses
naked and hairless mice with each other (cross 1). All the
offspring are phenotypically wild-
type.

A Better Way? As you can see, Punnett squares for phenotypes that involve several genes can get complicated. If you can recognize the patterns, you can make a mathematical model to figure out how common or rare a particular genotype or phenotype would be, depending on the number of genes involved. To do this, you begin by figuring out how many different combinations of alleles each Fparent could contribute to the F2 generation. When one gene-A-was involved, each parent could...

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...

In the gene that controls whether a cat’s ears curl, the dominant Cu+ allele produces curled ears, while the recessive Cu allele produces straight ears. In the gene that controls fur color, the dominant G+ allele produces black fur, while the recessive G allele produces grey fur. Both genes are on autosomes. Imagine a grey cat with curled ears mates with a black cat that has straight ears. Half the F1 offspring are black, while half are grey. All F1...

8. Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers & the recessive allele (w) codes for short whiskers. What percentage of offspring would be expected to have short whiskers from the cross of two long-whiskered seals, one parent is homozygous dominant and the other one is heterozygous? If one parent seal is pure long-whiskered and the other is short-whiskered, what percent of offspring would have...

Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...
