Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these statements is not true of inbreeding?
A
Desired traits can be passed to offspring.
B
Undesired traits can be eliminated.
C
Two closely related organisms are bred together.
D
Harmful recessive traits can never be passed to offspring.
Explanation: 

Detailed explanation-1: -Final answer: The incorrect statement regarding inbreeding is inbreeding selects harmful recessive genes that reduce fertility and productivity.

Detailed explanation-2: -Complete answer:-Inbreeding helps in the determination of harmful genes that are eliminated by the selection procedure.-Continuous inbreeding usually reduces fertility and even productivity, since there is no shuffling of DNA. This is called inbreeding depression.

Detailed explanation-3: -Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.

Detailed explanation-4: -Inbreeding tends to increase the occurrence of rare genetic diseases because related individuals are more likely to carry the same rare recessive allele, then have children that are homozygous for the allele and get the disease.
