Would all pigs in a litter have the same father? what about non identical human twins or triplets

2 answers:

5 0

In the female pig reproductive cycle, more number of eggs are released during one ovulation cycle. That is why, the number of offsprings born is more. The father of the litter is same single animal only. Because the process of fertilization of sperms with the eggs released happen in a time duration of few hours only.

In case of humans as well, the father is same. This is because in human reproductive cycle, only one egg is released majorly, accept the case of fraternal twins where two eggs are released and both are fertilized by two different sperms, but again from the same father.

Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart. 
This shows that the animals are similar and that they develop similarly, implying that they are related, have common ancestors and that they started out the same, gradually evolving different traits, but that the basic plan for a creature's beginning remains the same.

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution

Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

The cell contains a more concentrated solution than the solution in the container. The difference in concentration would produce an osmotic gradient that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers, and the other has white, terminal flowers

Debora [2.8K]

Answer:

Explanation:

The probability of producing plants with white axial flowers would be 1/16.

From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.

Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).

Pure-breeding red, axial flower = AABB

Pure breeding white, terminal flower = aabb

AABB x aabb

F1 genotype = AaBb - all red and axial

At F2:

AaBb x AaBb

Progeny

9 A_B_ red/axial

3 A_bb red/terminal

3 aaB_ white/axial

1 aabb - white/terminal

Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.

Amphiarthrodial joints display ___ movement than synarthrodial joints.

Misha Larkins [42]

The answer to this question would be more movement.

The amphiarthrodial joint is a joint that you will found in the rib cage. This joint doesn't have a synovial cavity and only allow a little movement.
But synarthrodial joints movement is practically zero. The example for synarthrodial joint would be suture in your skull. Skull joint in adult can't move so its volume can't be changed.
