Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.

The answers to the questions required for the design experiment above are :

  • If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases

  • If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.

  • The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.

  • The Dependent variable : Number of shark attacks

  • The Independent variable : The different number of elephant seals found.

  • Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.

  • John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.

The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.

The Experimental group are the portion of the subjects which are subjected to the treatment condition.

The Dependent variable is the measured variable is changes as the independent variables are tweaked.

Independent variable is the predictor variable, it causes a change in the output of the dependent variable.
