Let
• R = red
• r = white
• S = short stem
• s = long stem
Then two heterozygous (RrSs) parents can each contribute one of the following allele pairs:
RS, Rs, rS, rs
so that the genotypes of their offspring have the following distribution:
The probability of producing offspring with either the SS or Ss genotype is then 12/16 = 3/4.
In other words, there are 4² = 16 possible genotypes among the offspring, and each parent has a 1/2 probability of contributing the S allele. There are 2 cases to consider:
• both parents contribute the S allele with probability (1/2)² = 1/4
• one parent contributes the S allele while the other contributes the s allele, and this can happen in 2 ways with probability 2 × (1/2)² = 1/2
These events are mutually exclusive, so the total probability is 1/4 + 1/2 = 3/4.
Answer:
54 degrees
Explanation:
Plot point X on the left of point A on line l. Lines l and m are parallel, and segment AB is the transversal. Angles BAX and ABC are alternate interior angles, so they are congruent (same angle measures). Since segment BD bisects angle ABC, angles ABD and DBC are congruent. Therefore angle ABD is 108/2 = 54 degrees. In the diagram, we can also see that angle DAB is 180-108 = 72 degrees. Since interior angles of a triangle add up to 180, angle ADB is 180-72-54 = 54 degrees.
