Two animals were crossed in F1 generation: grey and brown. F2 consisted of 38 grey animals and 40 brown animals. Answer the following questions: a) what are the genotypes of organisms in F1 and in F2 generation? b) which color is dominant and which one is recessive? c) if two animals in F1 generation came from the same parents, what are all the possible genotypes that their parents could have?

Two peanut cultivars are crossed and their f1 progeny are selfed
to obtain an F2 generation. The first variety (represented in well
B) has a hairy stem. The second variety (represented in well C) has
a glabrous (hairless) stem. This trait is controlled by a single
gene, and hairy stems are completely dominant over hairless stems.
The DNA from both parents and the progeny is isolated, and a
portion of the gene controlling this trait is amplified using PCR
and...

In an experiment, homozygous dominant plants with purple flowers were crossed with homozygous recessive plants with white flowers. Mendel collected the seeds from this cross, grew F1-generation plants, crossed them to form a second generation, and then analyzed the plants of the resulting F2 generation. What results did he probably get? 1/2 the F1 and 3/4 of the F2 generation flowers were white 1/2 the F1 and 1/4 of the F2 generation flowers were purple 3/4 of the F1 and...

11. Two white-flowered strains of the sweet pea (Lathyrus odoratus) were crossed producing an F1 with only purple flowers. Random crossings among the F1 produced 97 progeny plants: 54 with purple flowers and 43 with white flowers. a) What is the phenotypic ratio of the F2 generation? b) What are the probable genotypes of the parental generation? c) How would you explain biochemically the relationship between purple and white flowers?

9. In snapdragons, red flower color is incompletely dominant to white and the heterozygote is pink. Normal broad leaves is incompletely dominant to narrow grass-like ones, and the heterozygous is intermediate width. IF a red-flowered, broad-leaved plant is crossed with a white-flowered, narrow-leafed one, list genotypic and phenotypic ratios of the following: a) Fi generation b) F2 generation 10. In humans, the allele for brown eyes (B) is dominant to the allele...

A male mouse from a true-breeding strain of hyperactive animals
is crossed with a female mouse from a true-breeding strain of
lethargic animals. (These are both hypothetical strains.) All the
progeny are lethargic. In the F2 generation, all offspring are
lethargic.
What is the best genetic explanation for these observations?
