netineya [11]

Answer:

The correct answer is -

A) BbTt x bbTt

B) .5^4 or 1/16 or 0.0625

Explanation:

As it is given that Brachydactylus and PTC tasters both traits are autosomal dominant conditions which mean only one allele would be enough.

For Branchydactylus and For tasting :  man and women will be heterogeneous.

Hence,

The Genotype of man = BbTt

The Genotype of wife = bbTt

b. Answer = 0.0625

For Branchydactylus:

Bb X bb

Possible genotypes:

B b

b Bb( Brachydactylus) bb(normal)

b Bb (Brachydactylus) bb (normal)

What is the best way to get information concerning an athlete's psychological strengths and weaknesses
Marrrta [24]

Answer:

oral interview and psychological inventories

Explanation:

Through degree training, psychology professionals are acquiring a set of tools, techniques, procedures and methods, from different theoretical schools, which are used to evaluate and intervene with the people they work with. Some call these people "patients", but in the field of sport, it is preferable to speak of "athletes" or simply "individuals", since the word patient, from the biomedical paradigm, refers to "passivity", to someone who suffers pain and expects the professional to "take it away." The individual with whom the sports psychologist works (the athlete or the team, the coach, the referee or any other “actor” in the field of sport) could say, is a worker, that is, that is not waiting for solutions provided by the psychologist, but works helped by him to improve his psychological skills for training and competition, without neglecting his health and personal well-being.

    The objective of this work is to present the psychological interview as a tool widely used by professionals who work in this field, but little studied, in relation to its objectives, how to carry it out and its scope.
