Alleles are two different forms of a single gene.
75-97% of beryllium-exposed workers who develop Chronic Berylliosis have a common HLA-DPB1 gene variant versus 30-45% of beryllium exposed workers who do not develop the disease.
Chronic berylliosis is a granulomatous disease caused due to beryllium exposure. Its symptoms include cough, fever, night sweats and fatigue.
The HLA-DPB1 gene belongs to a group of MHC genes called MHC class II. MHC class II genes provide information for synthesizing proteins that are present on the surface of certain immune system cells. These proteins attach to protein fragments or peptides outside the cell.
A definitive diagnosis of berylliosis is based on occupational history, positive blood or bronchoalveolar lavage (BAL) beryllium lymphocyte proliferation test (BLPT) and granulomatous inflammation on lung biopsy.

False. It is not a natural process. Humans choose the desirable features of a particular dog and selectively breed it. These dogs have not adapted to the environment. This selection is mostly based on cosmetic reasons or other desirable features. These dogs prob wouldn't be able to survive in the wild
The answer is 9 out of 16 offspring or 56.25 percent.
It is known that the in dihybrid cross (a cross between two different traits), the phenotypic ratio between the offspring, which parents are heterozygous, is 9:3:3:1.
R is an allele for round seeds, r is the allele for wrinkled seeds.
Y is the allele for yellow seeds, and y is the allele for green seeds.
It can be assumed the following:
9 - individuals with both dominant traits (RRYY) - plants with round and yellow seeds.
3 - individuals with the first dominant trait and the second recessive trait (RRyy) - plants with round and green seeds.
3 - individuals with the first recessive trait and the first recessive trait (rrYY) - plants with wrinkled and yellow seeds.
<span>1 - individual with both recessive traits (rryy) - plants with wrinkled and green seeds.</span>
