Explanation:
Also, change of climate influence the turtles and their evolution. In the future, these changes will be devastating. The beaches for nesting are disappearing and high temperatures are affecting their gender ratio.

Answer:
(b) 1/2Y 1/2y: Correct
Rest options are incorrect.
Explanation:
According to Mendel's law of segregation, the dominant and recessive alleles of a gene present together in a heterozygote do not get mixed and are segregated during gamete formation. Gametes are always pure and carry one allele of each gene. A gamete from a plant with "Yy" genotype cannot have two copies of either of the alleles.
The alleles of a gene are present on homologous chromosomes. Separation of homologous chromosomes carrying Y and y alleles each would result in the segregation of these alleles during gamete formation. The resultant 50% gametes would have a "Y" allele and the rest 50% would have a "y" allele.
