The galactosemia is a condition, in which the affected person is not able to metabolize the galactose sugar. This is a genetic disorder, inherited as an autosomal recessive trait. The homozygous dominant and the heterozygous individual do not show this condition. Only the individuals having homozygous recessive trait will show this condition.
Lets say allele G codes for galactosemia, and G codes for the dominant allele, and g code for recessive allele.

Answer:
Explanation:
Body waves are waves that moves within the earth. They propagate within the earth and have very interesting capabilities in different mediums.
There are two main types of body waves:
- Primary waves or P-waves; these types of waves can move within any material medium such as solid, liquid or gases. They are compressional waves in nature. They usually arrive in a seismic station first.
- Secondary waves or S-waves or Shear waves causes shearing. They move only in solids as liquids and gases cannot be sheared.
On a seismograph, wherever we cannot see an S-wave suggests that liquids or gases are present because they will not allow this wave to pass through.
Whenever we see P-waves, solids, liquids and gases are present.
This is a very important property used to investigate the subsurface.
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple <u>independent assortment inheritance according to Mendelian law.</u>
The result of crossing BbGg and bbgg is as follows (see the attached image)
<em>4 BbGg smooth and gray</em>
<em>4 Bbgg smooth and white</em>
<em>4 bbGg bumpy and gray</em>
<em>4 bbgg bumpy and white</em>
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
