What is the phenotype of BBRR?
F1: genotype BbRr and all will have the phenotype Black and Rough coatF2: punnett’s square for a dihybrid cross. The phenotypic ratio is 9:3:3:1.
How do you determine a genotype?
A Punnett square is one of the simplest ways to determine genotype. The square is actually a mini-chart used to determine the potential genotype for an offspring with respect to particular trait.
How do you find the genotype of a heterozygous?
For every gene, you inherit two alleles: one from your biological father and one from your biological mother. Together, these alleles are called a genotype. If the two versions are different, you have a heterozygous genotype for that gene.
What is the genotype of the heterozygote?
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What is the genotype of F1 generation?
The offspring of the RRYY x rryy cross, which is called the F1 generation, were all heterozygous plants with round, yellow seeds and the genotype RrYy.
How do you find the genotype of gametes?
To calculate the total number of gametes that are produced by a particular genotype, a specific formula 2n is used, where n= number of heterogeneous alleles that are found in the genotype. Here, the given genotype consists of two heterogeneous alleles Bb, and Cc while one homozygous allele is AA.
