Answer:

The correct answer is -50%

Explanation:

Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele

So, the heterozygous woman will be - Pp & the normal man will be - pp.  The presence of one allele of polydactyly will be able to show its effect as it is dominant.

Cross between heterozygous woman & normal man:

Gametes:

   P                              p

p Pp (Show polydactyly) pp (Normal phenotype)

p Pp (Show polydactyly) pp (Normal phenotype)

From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.

Does a dog like me? Is scientific or nonscientific
Basile [38]

Answer:

Non scientific.

Explanation:

Whether or not a dog likes you cannot be truly proven, and is more of a subjective query. A dog cannot really like or dislike a person. They can trust or not, they can be loyal or not, dominating or not, and such things, but “like” is an extremely opinionated term.
