Ionizing radiation, for example X-rays, gamma rays and alpha particles
Answer:
1. The parents genotypes could have been BO and AO
2. wire-hair
Explanation:
There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:
Blood type possible genotypes
Type A AA, AO
Type B BB, BO
Type AB AB
Type O OO
Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO for them to be able to produce a child with OO. a cross between these two could give rise to OO.
Question 2
Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).
thus, in a cross between homozygous wire haired and smooth haired, we will have:
homozygous wire haired homozygous smooth haired
P gen SS x ss
F1 gen. Ss
phenotype: wire haired

Patty (age 7) has symptoms that include a skin rash, fever slowed growth, fatigue, and swelling in the joints. She was diagnosed as having juvenile rheumatoid arthritis.
What is juvenile rheumatoid arthritis described as?
Juvenile rheumatoid arthritis is the most common kind of arthritis in children. It is characterized by heat and discomfort and causes the joints to expand. The duration of acute arthritis can range from a few weeks or months to years or even a lifetime. It can also be persistent. IA types include autoimmune and autoinflammatory illnesses. This suggests that the immune system, which is meant to fight off viruses and pathogens, becomes confused and attacks the body's cells and tissues. The doctor can suggest blood testing for C-reactive protein and erythrocyte sedimentation rate. These blood tests evaluate inflammatory markers or markers of inflammation.
