Answer:
Gastrulation takes place after cleavage and the formation of the blastula and the primitive streak. It is followed by organogenesis, when individual organs develop within the newly-formed germ layers. Each layer gives rise to specific tissues and organs in the developing embryo.Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body. The endoderm gives rise to the gut and many internal organs.

Answer:
The correct option is <em>B. 25 %</em>
Explanation:
A heterozygous type can be described as the type in which both the alleles of a gene are different. If both the alleles of a gene are similar in an organism, then the person is said to be homozygous for the trait.
In the above question, two heterozygous parents are to be cross- bred to check the probability of them producing homozygous alleles (AA).
A punnet square made will show the following results:
A O
A AA AO
B BA BO
Hence, there will be 25% chance that the offspring produced could be homozygous AA.
