Mendel used single gene (or monohybrid) experiments to describe his law of segregation. He used _______ characters (or dihybrid)
allochka39001 [22]

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.

Kyle is holding a bag of 250 jelly beans. When Mark takes out two jelly beans, Kyle is not able to tell a difference.
Fudgin [204]

Answer:

Sensory adaptation.

Explanation:

Hello.

In this case, after the removal of the two jelly beans, Kyle has now 248 jelly beans which is a slightly neglectable difference, it means that the answer is sensory adaptation since it refers to a decrease in the sensitivity to a stimulus due to the constant exposure to it, which also reduces our awareness when a neglectable change happens.

This is proved since Kyle was constantly holding the bag so a difference of two jelly beans will be almost neglectable making the sensory adaptation the reason behind this.

Regards.

The first bird that evolved the ability to fly now had habitats never before available and soon branched out into many different
dolphi86 [110]

Answer:

The correct answer is- adaptive radiation

Explanation:

Adaptive radiation is the evolutionary process which allow the evolution of many species from a single species because some population of that species get into an environment which is different from their old environment in terms of food availability, predators, etc.

So the first bird that evolved the ability to fly branched into many different species due to habitat change is an example of adaptive radiation. The most famous example of adaptive radiation is Darwinian finches which evolved from an ancestral species of south America that reached Galapagos island.
