A man is brachydactylous (very short fingers; rare autosomal dominant), and his wife is not. Both can taste the chemical phenylt
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)

The probability of a single child being Branchydactylus = 2/4 = 0.5

So,  Probability of all 4 child being Branchydactylus = .5 x .5 x .5 x .5 = 0.0625

In humans the genetic commonality of height and skin tone is that they are both
lubasha [3.4K]

Answer:

In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>

Explanation:

Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.

Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.
