When performing Dihybrid crosses, you must foil the parent's genotypes first to figure out their 4 gamete's alleles. If one parent's genotype is BbTt for having brown hair and is tall, what are their 4 genotypes that would go above the dihybrid cross punnett square?
Bt Bt, bT, bT
Bt, bt, Bt, bt
BT, Bt, bT, bt
BT, bt, BT, bt
When performing an original monohybrid cross following Mendel's laws, what percent of a pea plant's offspring would be round if one parent had an "Rr" genotype and the other had an "rr" genotype? "R" is the allele for round, and "r" is the allele for wrinkly.
