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.
The long nephron loops of the juxtamedullary nephrons are located in the renal medulla.
<u>Explanation:</u>
The kidneys are the major filtering units that are present in the body. The kidneys filter the ions of the body and expel the waste of the body and retain the required ions in the body.
The nephrons are the functional units of the kidney that are majorly responsible for the filtering action. The longer the nephron loops are more concentrated urine is expelled from the body.
Answer: If you break the two terms down, "intraspecific" just means within a species, while "interspecific" means between them. Consequently, interspecific competition is all about competition between two or more species, while intraspecific competition involves different individuals of the same species.
