Example of post-zygotic barrier?
Post-zygotic barriers are reproductive barriers that occur after fertilization, such as hybrid inviability or hybrid sterility. An example of a post-zygotic barrier is when a hybrid offspring fails to develop properly or is unable to reproduce, reducing the fitness of the hybrid offspring.
The type of reproductive barrier that occurs when two species mate but produce sterile hybrids is referred to as?
a post-zygotic barrier
Why is the yolk sac of a chick embryo smaller than a human embryo?
No , reverse is true .
How long is the zygotic period?
The zygotic period, also known as the pre-embryonic stage, lasts about two weeks following fertilization. During this time, the fertilized egg (zygote) undergoes a series of cell divisions as it travels down the fallopian tube toward the uterus. By the end of this period, the zygote develops into a blastocyst, which then implants into the uterine lining, marking the beginning of the embryonic stage.
Why is the chick embryo smaller than that of a human?
Embryo size depends upon size of animal .
What are the types of embryo?
two type of embryo 1) zygotic embryo 2) nonzygotic embryo
When does the zygotic period end?
The zygotic period, also known as the pre-embryonic stage, ends when the fertilized egg (zygote) successfully implants into the uterine lining, typically around 6 to 10 days after fertilization. This marks the transition to the embryonic period, where the zygote develops into an embryo. During the zygotic period, the zygote undergoes cell division and differentiation as it travels through the fallopian tube toward the uterus.
Where does mitosis occur in zygotic life cycle?
Mitosis occurs during the zygotic life cycle in the zygote stage. After the fertilization of egg by sperm, the zygote divides through mitosis to give rise to a multicellular embryo. This process of mitotic division continues to generate all the cells of the developing organism.
When did Gorky's Zygotic Mynci end?
Gorky's Zygotic Mynci ended in 2006.
When was Gorky's Zygotic Mynci created?
Gorky's Zygotic Mynci was created in 1991.
Are conjoined twins mono-zygotic or di-zygotic?
Conjoined twins are monozygotic, meaning they develop from a single fertilized egg that splits incompletely during early development.
What is embryo seeds?
Embryo seeds, often referred to as zygotic embryos, are the initial stages of seed development that arise from the fertilization of an ovule in plants. They contain the genetic material from both parent plants and will develop into a new plant when conditions are favorable. In seed biology, these embryos are crucial for the propagation of plant species, as they contain the necessary structures to grow into a mature plant.

Which letter in this figure showing a zygotic life cycle indicates where meiosis occurs?
The letter that indicates where meiosis occurs in the zygotic life cycle is usually represented by the letter "C", which represents the formation of spores through meiosis.
What is post zygotic?
You may mean post zygotic isolation/barrier to interbreeding between species. Sterile hybrids, such as mules are a good example of this. The zygote can form from the union of two gametes, but the mature organisms can no longer produce progeny usually due to chromosome mismatch.
What is the fate of embryo in the embryo sac?
no
