Chromosome segregation
If the character is governed by a single allele and it is dominant, than its probability to be in the gamete is 75%.
Answer:
B
Explanation:
A denotes a dominant allele, a denotes a recessive allele. Therefore, if there are two a alleles (aa) the recessive phenotype will be presented. However, the presence of the A allele (either as heterozygous Aa or homozygous AA) will present the dominant phenotype.
a) AA will present dominant phenotype, aa will present recessive phenotype
b) AA will present dominant phenotype, Aa will present dominant phenotype
c) Aa will present dominant phenotype, aa will present recessive phenotype.
