Answer: For three traits inherited in a dominant/recessive pattern, the probability of an offspring in a trihybrid cross between parents heterozygous for all three traits to be recessive at exactly two of the three loci is 23/64.
Explanation: Let A, B and C represent the dominant alleles and a, b and c represent the recessive alleles. The genotype of each of the parent will be AaBbCc since it has been said to be heterozygous for all the three traits. There are eight (8) possible different types of gametes from each of the genotype. This can be calculated using 2^n where n is the number of heterozygous loci.
The number of heterozygous loci in the genotype AaBbCc is three (3). 2^3 = 8. The gametes are;
ABC
ABc
AbC
Abc
aBC
aBc
abC and
abc.
Therefore, sixty-four possible offsprings are expected from the cross AaBbCc x AaBbCc.
Out of these offsprings, twenty-three (23) are expected to be heterozygous at two loci as boldly shown in the attached image.

Explanation:
Look at the picture below
If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.
<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
- An organism that preys on other species in order to consume them as food is referred to as a predator.
- Prey is a term used to describe an organism that a predator kills.
- An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
- Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
- Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.
Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.
