Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
No. Dominant alleles always hide recessive. Think of it this way, dominant as in, the leader. That helps me remember that they take over. :) good luck !
a type of plant
Yes in homozygous recessive condition.
no
Wrinkled seeds are recessive The F1generation carried recessive alleles.
recessive alleles are the ones with small letters, for example in Rr, the recessive is the r.
Individual alleles control the inheritance of traits. Some alleles are dominant, while others recessive.
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both a dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.
Dominant alleles are shown by a capital letter and recessive alleles are lowercase letters.
Wrinkled seeds are recessive The F1generation carried recessive alleles.
An organism with the alleles BB would be homozygous dominant.
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
recessive alleles are the ones with small letters, for example in Rr, the recessive is the r.
Individual alleles control the inheritance of traits. Some alleles are dominant, while others recessive.

If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.
