Answer:
50%
Explanation:
According to this question involving a gene coding for seed shape in pea plant, the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). This means that a heterozygous pea plant (Rr) will have a round seed shape.
If a plant that is heterozygous for seed type (Rr) is crossed with one that has only homzygous wrinkled seeds (rr), the following gametes will be produced by each parent plant:
Rr - R and r
rr - r and r
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
Rr, Rr, rr and rr
Rr = round seed offsprings
rr = wrinkled seed offsprings
Since 1 out of 2 offsprings has wrinkled seeds, 1/2 × 100 = 50% is the percentage of offsprings expected to have wrinkled seeds.
Answer:B
Explanation:THE NET FORCE ACTING ON THE CRATE IS ZERO.
Pea Plants had very similar characteristics to human beings when it came to genetics.
Answer:
An autoimmune disease is the result of the immune system attacking its own healthy cells and tissues. An example of this disease is rheumatoid arthritis, which attacks the joints; hence, becoming them to be inflamed.
Explanation:
To counteract this effect, painkillers, steroids, and anti-inflammatory drugs are taken to reduce this inflammation and pain in the joints. Physical therapies and surgeries are also performed to treat this disease.
