AND TEENAGE MUTANT NINGA TURTLES
Explanation:
Answer: (B) Pre-zygotic; post-zygotic.
Explanation:
Prezygotic isolation occurs before fertilization of eggs. It occurs between the two sex gametes and deter sexual reproduction between different species.
However, individuals are considered to be diverge on the phylogeny tree and different species, when they cannot reproduce.
Mechanisms of prezygotic isolation include habitat isolation, gamete isolation, mechanical isolation, behavioral isolation, and mating seasons.
Whereas, postzygotic isolation prevents the formation of fertile offspring. This phenomenon leads to production of an hybrid offspring from different species and this is a form of speciation in nature.
Mechanisms of postzygotic isolation include hybrid inviability, hybrid breakdown, and hybrid sterility.
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.
<h3>What is heterozygous?</h3>
The occurrence of different types of alleles is referred to as heterozygous condition.
A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.
The missing options of the question are:
- Yy ´ yy
- YY ´ yy
- Yy ´ Yy
- yy ´ yy
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.
Thus, the correct option is A.
