Which of the following is an example of a heterozygous genotype?
The alleles such as TT or tt, RR or rr, and so on.The alleles such as TT or tt, RR or rr, and so on.they are also Tt Rr etc
How many alleles does a pea plant gamete have for the height gene?
TT or Tt
A pea plant has a tall stem what are its possible genotypes-?
Is tall dominant? You didn't say. Let's assume it is. Therefore, as long as a dominant allele is one of the two alleles an organism has for every trait, and we let "R" stand for dominant tall and 'r' stand for recessive short, then either an RR or Rr genotype will result in a tall phenotype.
Two organisms each with the genotypes Tt Gg mate The chance of producing an offspring that has the dominant phenotype for height T and the recessive phenotype for color g is?
The chance of producing an offspring with the dominant phenotype for height (Tt) and the recessive phenotype for color (gg) is 1/4 or 25%. This is because the genotype for height is determined by one gene and the genotype for color is determined by a different gene, so they are inherited independently of each other.
When two pea plants that are heterozygous for yellow peas are crossed.the resulting offspring have a genotypic ratio of?
Because heterozygous means that the parents contain both dominant and recessive genes the offspring will be 75% tall and 25% short. If you were to draw the punnett squares you would see that there are 3 possible children one with only dominant tall traits two with both dominant and recessive traits and one with only recessive traits.
