Zygotic and nucellar embryos can occur in the same seed, and a zygotic embryo can divide to produce multiple embryos.
22.
Finally, these embryos are placed onto another medium where they develop into normal plants such as any natural zygotic embryos.
23.
They began working on new material in 2005, along with former Topper and Gorky's Zygotic Mynci drummer Peter Richardson.
24.
Bird song is an integral part of bird courtship and is a pre-zygotic isolation mechanism involved in the process of speciation.
25.
Studies of the mouse counterpart suggest that the expression of this gene may be regulated during oocyte maturation and preimplantation following zygotic gene activation.
26.
Hybrid dysfunction ( sterility and inviability ) is a major form of post-zygotic reproductive isolation, which occurs in early stages of speciation.
27.
He has also contributed to solo albums by Gorky's Zygotic Mynci front-man Euros Childs and was part of his touring band.
28.
The second way is found in birds and mammals, where germ cells are not specified by such determinants but by signals controlled by zygotic genes.
29.
At Adam Walton's request, the band recorded a BBC Introducing session with John Lawrence of Gorky's Zygotic Mynci in early 2011.
30.
In some cases, the addition of an extra Y-chromosome results from nondisjunction during cell division during a post-zygotic mitosis in early embryonic development.
