Answer:

The first 2 weeks of development is the germinal period. The germinal period begins with conception and ends when the blastocyst is fully placed into uterine tissue. Next, the embryonic period lasts from implantation until about 8 weeks from the time of conception.

Explanation:

The third thru the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.

Development and Applications of a High Throughput Genotyping Tool for Polyploid Crops: Single Nucleotide Polymorphism (SNP) Array.

Polypoid species play significant roles in agriculture and food production. Many crop species are polyploid, such as potato, wheat, strawberry, and sugarcane.

Genotyping has been a daunting task for genetic studies of polyploid crops, which lags far behind the diploid crop species.

Single nucleotide polymorphism (SNP) array is considered to be one of, high-throughput, relatively cost-efficient and automated genotyping approaches.

However, there are significant challenges for SNP identification in complex, polyploid genomes, which has seriously slowed SNP discovery and array development in polyploid species.

Ploidy is a significant factor impacting SNP qualities and validation rates of SNP markers in SNP arrays, which has been proven to be a very important tool for genetic studies and molecular breeding.

This review presents a complete overview of SNP array development and applications in polypoid crops, which will benefit the research in molecular breeding and genetics of crops with complex genomes.

Carbon and hydrogen have similar electronegativities and combine together to form hydrocarbon molecules. What type of bonds form

egoroff_w [7]

The type of bond formed between carbon and hydrogen is NON POLAR COVALENT BOND.
Covalent bond involves sharing of atoms between two elements; each element will donate electrons which will be equally shared by the elements involved. In the case of carbon and hydrogen, carbon has four electrons in its outermost shell, therefore it will form a covalent bond with four atoms of hydrogen each of which will donate one electron.
