in the f2 generation of mendels crosses, all plants had the dominant trait. half of the plants had the dominant allele. all plants had both the dominant and recessive alleles. one in four plants had two alleles for the recessive trait.

in the f2 generation of mendels crosses, all plants had the dominant trait. half of the plants had the dominant allele. all plants had both the dominant and recessive alleles. one in four plants had two alleles for the recessive trait.

Answer

Brief Explanations:

In Mendel's experiments, when the F1 generation (heterozygous) self - crosses to produce the F2 generation, using a Punnett - square analysis for a single - gene cross (monohybrid cross), the genotypic ratio is 1:2:1 (homozygous dominant:heterozygous:homozygous recessive). This means that one in four plants has the homozygous recessive genotype, which has two alleles for the recessive trait.

Answer:

one in four plants had two alleles for the recessive trait.
