Answer: Autosomal recessive

Explanation:

Autosomal recessive is the genotypic type of expression of traits. In an autosomal recessive disorder, 2 copies of an abnormal gene must be present which are responsible for the development of the trait.

The parents of the individual that have an autosomal recessive each must carry a copy of a mutated gene or deffected or abnormal gene but they do not show signs and symptoms of the condition. The autosomal recessive disorders are not seen in every generation of the family which is affected.

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,

myrzilka [38]

Answer:

A) The frequency of the dominant allele, C $= 0.4376$

B) frequency of the heterozygous genotype, Cc $= 0.2461$

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Number of students with curly hair is $37$

Thus frequency of genotype "CC"

$= q^{2} = \frac{37}{117} \\= 0.3162$

Thus, frequency of allele "q"

$= \sqrt{0.3162} \\= 0.5623$

As per Hardy Weinberg's first equation-

$p+q=1$

Substituting the value of q, we get -

$p+0.5623=1\\p= 0.4376$

As per Hardy Weinberg's second equation -

$p^2+q^2+2pq=1\\$

Substituting the values of "p" and "q" we get -

$0.4376^{2} + 0.3162+2pq = 1\\2pq = 0.2461\\$

Hence,

A) The frequency of the dominant allele, C $= 0.4376$

B) frequency of the heterozygous genotype, Cc $= 0.2461$

skad [1K]

Answer:

Option C

Explanation:

Brent will opt to work with an individual who has the desired characteristics to meet the work requirement and could also go along with efficient team building. Thus, in case if both Ken and Darwin have similar characteristics, then Brent would prefer to work with both the person irrespective of their color. Physical characteristics will not impact Brent decision for choosing one amongst the two.

Hence, option C is correct
