<span>Answer: 16 combinations
A fruit fly has four pairs of chromosomes in its cells. Assuming all pair is heterozygotes, each pair of the chromosome can be divided into two possible combinations. So, if there are 4 pairs then the possible combination would be 2 * 2 * 2 * 2= 16 possible combinations.</span>
The answer is actually d I mean atleast I think
The action is Fixed Action Pattern. It is a highly typecasted sequence of behaviors that, once begun, is usually carried to completion. It is triggered by a sign stimulus. The egg outside the nest is the stimulus.b <span>It is performed virtually the same by all regardless of environmental conditions. </span> Even if the egg is removed or slips away, she completes the behavior by returning an "imaginary" egg to the nest.
The correct answer is B). The potato cells lost water to the surroundings.
The salt water solution is hypertonic as compared to cell of a potato slice. In other words cells of potato slice is hypotonic to salt solution. Water always moves from hypotonic to hypertonic solution if they separated by semipermeable membrane. Thus, when potato slice is dipped into salt water, ex-osmosis that is water will move out of the potato slice into the salt solution. As a result into shrinking of potato slice.
Answer:
Law of Independent assortment
Explanation:
Gregor Mendel, who was regarded the father of Genetics, discovered principles that governs inheritance in his experiments. He discovered that the alleles of a gene will separate into gametes when he performed a crossed involving a single gene or character like height, pea color etc. He proposed his law of segregation based on this.
However, he considered two characters or genes in his cross, which he called a DIHYBRID cross. He discovered that the alleles of each different gene separates into gametes independently of one another i.e. without one gene influencing the other in each gamete. He called this principle his LAW OF INDEPENDENT ASSORTMENT.
He obtained a 9:3:3:1 phenotypic ratio for the F2 dihybrid offsprings which is only possible if each gamete equally likely contains two alleles of the two different genes in different combinations.
