Worked Solution & Example Answer:With respect to this gene A - VCE - SSCE Biology - Question 9 - 2002 - Paper 1

Step 1

an individual could have one of eight different genotypes.

Answer

This statement is generally true for certain genes that have multiple alleles. For a gene with multiple alleles, the number of genotypes is calculated using the formula for combinations, considering the different combinations of alleles that can occur.

Step 2

an individual could have one of six different phenotypes.

Answer

The number of phenotypes may not directly correlate to genotypes, particularly in cases of incomplete dominance or co-dominance. Therefore, this statement may or may not hold true depending on the specifics of the gene in question.

Step 3

a child could have protein A even if both parents lacked protein A on their red blood cells.

Answer

This statement is false. If both parents lack protein A, they cannot pass on the allele responsible for producing protein A, hence their child cannot have protein A.

Step 4

a child with neither protein A nor B could have a mother with protein A and a father with protein B.

Answer

This statement is true as the child could inherit alleles that result in a phenotype lacking both proteins. If both parents carry recessive alleles for the absence of proteins A and B, the child could express neither.
