It draws a conclusion based on what would best explain one's observations.
Inference is the process where logical consequences evolve from premises that are assumed to be true. Knowledge backed with observations and reasoning as evidence is used to make conclusions. It is also referred to as an educated guess and is not necessarily factual.

DNA 2: TAC CCG ACG GGC GAT AGT TTT
a) What types of mutation have occurred in each of the DNA 1 and DNA 2 sequences?
b) Explain how these mutations affect the amino acid sequence produced and the overall effect on the final protein. Which mutation will cause the most disruption to the overall protein structure and why?
A) The sperm cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
B) The egg and sperm cells contribute equal amounts of mitochondrial DNA to the zygote.
C) The egg cell donates most of the material in the cytoplasm to the zygote, including mitochondrial DNA.
D) The sperm cell donates most of the DNA in the nucleus to the zygote, including mitochondrial DNA.
Answer:
The answer should be C
Explanation:
The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.
The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.
Answer:
Explanation:
The disease sickle cell anemia is caused by homozygosity for a mutation:
Albinism is a recessive trait:
The genes S/s and A/a are linked and separated by 1 map unit.
Remember that 1 mu means that 1% of the gametes produced by an individual will be recombinant.
Son: Sa/sA
The gametes he can produce are:
Since the frequency of recombination is 1% (or 0.01), each recombinant gamete has a frequency of 0.005 (since there are two possible recombinant gametes).
The parental gametes will appear with a frequency of 0.99, each of them with a frequenct of 0.495.
Daughter: SA/sa
The gametes she can produce are:
In order for them to have an albino child with anemia (sa/sa), the gamete sa from each parent had to be produced and fused into the zygote. Since the production of gametes by each parent is an independent event, the probability of having sa/sa offspring can be calculated as:
Prob. sa gamete son × Prob. sa gamete daughter = 0.005 × 0.495 = 0.0025
The probability that a child of theirs will be an albino with sickle-cell anemia is 0.25%
