Skin colour in dolphins is determined by a single gene showing incomplete dominance giving rise to 3 phenotypes Brown, Pink & White. A survey of a large population of dolphins was carried out and the phenotypes recorded. However a student who had some of the data stored on their phone fell overboard and unfortunately the data was lost. The only data saved was that the brown homozygous dominants (BB) were 64% of the population . ALL WORKING MUST BE SHOWN a) What would be the percentage of pink heterozygotes and white homozygotes?   b) What percentage of the gametes that give rise to the next generation of dolphins in this population will contain the b allele?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
