Can two organisms with the same phenotype have different genotypes?
Annette [7]

Let's look BB and Bb

They both have the dominant trait which means they both have the same physical appearance (phenotype) , but while BB has both dominant and Bb has one dominant and one recessive that means that although Bb has the same phenotype as BB, it has a different genotype because it has a bit different genetic makeup

Tay–Sachs disease is an autosomal recessive disorder. Homozygous recessive individuals lack a key enzyme called hexosaminidase A
myrzilka [38]

Answer:

0.033

Explanation:

Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:

  • TT = normal
  • Tt = carrier
  • tt = Tay-Sachs disease

I will use <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> allele.

If the population is in equilibrium, the frequency of the tt genotype is q².

q^2 = 1/3600\\\\q=\sqrt{1/3600} \\\\q=1/60=0.017\\\\and\\p + q = 1\\p=1-q\\p=0.983

The frequency of the Tt genotype is 2pq.

2pq= 2*0.983*0.017\\2pq=0.033

The Tay–Sachs carrier frequency will be 0.033
