Explanation:
Answer:
The punnet square can be completed as follows:
C C
A AC AC
A AC AC
The results from the punnet square show that all of the offsprings form will be agouti as agouti is the dominant trait. However, the genotype of the offspring will be heterozygous carrying the alleles AC.
A dominant trait is the trait which arises due to a dominant allele. The dominant allele masks the effect of the recessive allele.
A heterozygous genotype occurs when the alleles of a gene are different.
Answer:
The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.
Explanation:
Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.
The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.
Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.
