Gastrulation, when the cells organize themselves into an embryo occurs 2 weeks after conception. What do the 3 layers of cells g

Travka [436]

Answer:

Gastrulation is the process where the developing embryo forms the process of the 3 germ layers. These germ layers are formed due to the movement of the single-layered blastula. Gastrulation starts during the third week of the human embryo.

The three germ layers give rise to different organs of the fetus. The 3 layers are ectoderm or outer layer, mesoderm or middle layer, and endoderm or inner layer.

These 3 germ layers give rise to different organs of the human fetus. Ectoderm forms epidermis, skin, hair, olfactory organs, eye lense. glands like pituitary. Sensory nerves, skeleton, pigment cells are also formed from ectoderm.

Ectoderm also forms a neural tube that further divides to form the brain, spinal cord.

Mesoderm form the vertebral column, skeletal muscle, excretory organs, reproductive organs. It also forms blood cells, blood vessels, body cavity or coelom.

The inner layer endoderm gives rise to the lining of the digestive tract, liver, pancreas, bladder, etc.

Suppose a gene has two alleles, one of which is dominant over the other. An individual whose genotype is for the recessive allel

Trava [24]

Answer:

This question is incomplete, the options are:

A. Two copies of the allele that determines phenotype whenever the allele is present

B. Two copies of the allele whose effect is hidden unless the other allele is absent

C. One copy of the allele that determines phenotype when present and one copy of the other allele

D. One copy of each of two alleles that both contribute equally to determining phenotype

The answer is B.

Explanation:

According to Gregor Mendel, a Gene comes in two alternative forms called ALLELES. One allele called the DOMINANT ALLELE is capable of masking the phenotypic expression of the other called the RECESSIVE ALLELE. The dominant allele will always express itself whenever it is present. However, a recessive trait will only be expressed when two alleles for recessiveness occur in the gene.

An individual whose genotype is for the recessive allele will have two copies of the allele whose effect is hidden unless the other allele is absent. This means that in that particular gene, the two present alleles will be recessive alleles.
