Answer:
Option B is correct
Explanation:
Given -
"Ability to taste the chemical phenylthiocarbamide" is autosomal dominant while its inability is recessive.
Autosomal dominant means that even if one l
Let the allele for dominant trait i.e "Ability to taste the chemical phenylthiocarbamide" be represented by "T"
and the allele for recessive trait i.e "Inability to taste the chemical phenylthiocarbamide" be represented by "t"
Genotype of a taster woman with a nontaster father is Tt
Genotype of a taster man who in a previous marriage had a nontaster daughter is also Tt
Tt * Tt
TT, Tt, Tt, tt
Therefore probability of being a taster is
, and the probability of being a nontaster is ![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Probability that their first child will be a taster girl is equal to
Probability of being a taster
Probability of being a girl
![\frac{3}{4} * \frac{1}{2} \\=\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%5C%5C%3D%5Cfrac%7B3%7D%7B8%7D)
Thus, option B is correct
Answer:
Precipitates of BaSO4 will be formed.
Explanation:
Most of the sulphates are soluble but barium sulphate is not soluble, it forms precipitates in the mixture. This reaction is of much industrial importance for production of barium sulphate and is used in paints too.
It’s the third one, anaphase metaphase prophase and telophase
C. because stimuli is how your body responds to something, and in this case, someone's heart rate increases WHEN their blood oxygen drop. Do you see how it responds? ;-)
