For three traits inherited in a dominant/recessive pattern, what is the probability of an offspring in a trihybrid cross between
AleksandrR [38]

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.

I won’t be willing to eat this altered genetically crops because they are much harmful to humans. For example some links term genetically crops do gluten disorders that affect millions of Americans. Again there are multiple toxins which are from genetically altered crops which detect in real and fetal blood.

Negatives.

Genetically altered crops have got DNA and can be transferred to people who eat them.

Genetically altered crops can cause modified corn to rat tumours.

They cause human breast cancers induced by glyphosate via estrogen receptors.

In pigs genetically crops cause severe stomach inflammation and enlarged uteri.
