Question

On an extraterrestrial planet, which had organisms that reproduced with DNA the same way that organisms on Earth do, green little organisms have eyes that are triangular or round shaped. Triangular eyes are dominant to round eyes. A cross was performed between two of these extraterrestrials with the genotypes IT and tt. Predict the probability that an offspring would have round eyes.
2:4
1:4
4:4
0:4​

Answer 1

The correct answer is 0:4​ i.e. No offspring would have round eyes.

According to Mendel's Law of Inheritance-

• Triangular eyes are dominant character, genotype = TT
• Round eyes are recessive character,  genotype = tt

A cross was performed between two of these extraterrestrials with the genotypes TT and tt.

TT × tt = Tt

therefore F1 generation would be Tt i.e. all the offspring would have Triangular eyes with genotype Tt because it is the dominant character .

And there will be no offspring with round eyes because it is the  recessive character .
