This statement would be false if this is a true or false question. because the organism is less likely to acquire traits that would benefit its survival.
Linked genes are genes that are likely to be inherited together because they are physically close to one another on the same chromosome. During meiosis, chromosomes are recombined, resulting in gene swaps between homologous chromosomes.
Answer:
The correct answer is D Sister Chromatids may not attach to each other.
Explanation:
Centromeres are the specific point to which the sister Chromatid binds.That means Centromere function to hold the sister Chromatids.
Now according to the question if mutation causes formation of defective centromere then the normal functioning of that centromere will be hampered.
As a result the sister chromatid may not attach to each other.
The options are incomplete and have been listed incorrectly. Complete question has been attached.
Answer:
C) Dd and Dd
Explanation:
It is given that deafness is a recessive trait which means that Dr. Smith has genotype dd since a recessive trait can only be expressed when both the alleles in genotype are recessive. However, his parents are normal. So his parents can have DD or Dd genotype. Dr. Smith has obtained one recessive d allele from his father and other recessive d allele from his mother. Thus, the parents should have Dd genotype and the correct option is c.
