The answers are A) ectoderm and B) endoderm.

Fertilization is a fusion of male and female gametes which leads to the formation of a zygote. The zygote undergoes mitosis and transforms into a single-layered blastula. Gastrulation is a transformation of the blastula into a two-layer or three-layer gastrula. Cnidarians are a diploblastic animal because their gastrula has only two layers - endoderm and ectoderm.

Describe the relationship between genotypes and phenotypes
MA_775_DIABLO [31]

Answer:

Genotype is the potential, it is the set of genes.

Phenotype is the expression of those genes, showing the dominant/ activated gene.

For example, my mother and members of her family are short with hazel eyes and dark hair.

My dad and his family are tall, with brown eyes and dark hair.

I will have genes for height that vary- short or tall. I will have genes for eyes hazel or brown.

I will have genes for hair- dark.

You don’t know, based on what i’ve told you, what my height or eye colour is. That’s my genotype.

I am tall, with hazel eyes and dark hair. That’s my phenotype.

This is really over simplified, but it should help you understand.

Genotype is the blueprint/ building plans. Phenotype is the building.

saveliy_v [14]

Answer:

B. Genotypes

Explanation:

The genotype of an organism refers to the genetic makeup of that organism. It is the combination of all the genes contained on the chromosomes of that organism. Gregor Mendel, who is considered to be the Father of Genetics, discovered that certain factors are responsible for the physical characteristics of organisms and that they can be transferred from one generation to another. These factors are called GENES. Genes are located on X-shaped structures called chromosomes.

Hence, the isolation of chromosomes taken from tortoise blood samples refers to recording their GENOTYPE (genetic constituent).
