Answer:
Immunodeficiency disorders prevent your body from fighting infections and diseases. This type of disorder makes it easier for you to catch viruses and bacterial infections. Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with. whereas Opportunistic infections (OIs) are infections that occur more frequently and are more severe in people with weakened immune systems, including people with HIV. Many OIs are considered AIDS-defining conditions.

The image provided is not clear, however, the correct and clear image is attached with the answer:
Answer:
The correct answer is - 100 %
Explanation:
As we know DMD or Duchenne Muscular Dystrophy is a sex-linked recessive disorder and according to the given pedigree, it is clear that Individual I-1 is a normal male and 1-2 is a female who has two defective genes of the disorder as if she had only one defective gene she would have a carrier for the disorder.
All gametes produced by both male and female would be -
Male - X and Y
Female - Xd and Xd
Therefore all the male offsprings or son will get one defective gene Xh from the mother for sure and a Y chromosome from the father. All daughters will also carry one gene Xh that is defective from the mother and normal X from the father but would be carriers for the disorder.
Answer:
The correct answer is option B: "50%".
Explanation:
The classical Mendel's Law of Segregation states that each individual has two alleles, one that is passed from each parent. In this example the W gene has a W dominant allele and one w recessive allele. If a Ww heterozygous male is mated with a ww homozygous recessive female there is a 50% chance that the offspring will be heterozygous. This result considering that Gregor Mendel's rules dictate that the offspring's genotype of the aforementioned crossing will be 50% Ww and 50% ww.
