Understanding Phenotypes in Monohybrid Cross
What Happens in a Monohybrid Cross?
In genetics, a monohybrid cross involves the crossing of two individuals that are heterozygous for a single trait. This means that each parent carries two different alleles for the trait, one dominant and one recessive.
Phenotype Frequency in Monohybrid Cross
When two heterozygous parents are crossed in a monohybrid cross, the offspring inherit one allele from each parent. The possible combinations are BB, Bb, Bb, and bb.
Black= B
Brown= b
Black is dominant over brown.
Therefore, 75% of the offspring will exhibit the black phenotype, while the remaining 25% will exhibit the brown phenotype.
Answer:
In a monohybrid cross when two heterozygous parents are crossed, 75% of the offspring will have the black phenotype.
Bb x Bb = BB, Bb, Bb, and bb
Black= B
Brown= b
Black is dominant over brown.
75% of the offspring is black while 25% is brown
In a monohybrid cross when two heterozygous parents are crossed, 75% of the offspring will have what phenotype? In a monohybrid cross when two heterozygous parents are crossed, 75% of the offspring will have the black phenotype.
