Based on base substitution rates, which of the following is likely to be true? P(A/G) + P(A/T) OP(A/G) ≥ P(A/T) P(A/G) = P(A/T) P(A/G) ≤ P(A/T)

In investigating whether stress is a factor in aging, telomere length was measured in women with chronically ill children, and compared to the number of years since the child's diagnosis. Use the following summary data to calculate the correlation coefficient between telomere length and chronocity: Summary data: Sum of products: -11.564 Sum of squares for chronicity: 311.422 Sum of squares for telomere length: 2.499 Total sample size: 39

Could someone please help me with this grade 11 bio dihybrid cross problem in detail and how to solve this question, using a strategy? Assume that curly hair (C) is dominant to straight hair. Albinism (P ) is recessive to normal skin pigmentation. A woman who is heterozygous for curly hair and albinism has a child. The father is homozygous dominant for curly hair and has albinism. (a) Determine the possible phenotypes for their child. (double-crossing, Puneet square)(b) Calculate the four different probabilities of a child beingboth a male and of each phenotype.(c) What is the probability that the child will expressalbinism and have curly hair like his father?

b) Following figure is showing the DNA fingerprint analysis on the one locus of a man with four children. Which lane contains the DNA of a father? Why did you select that lane? 1 234 5 A.

Using the observed counts for each genotype, how do you find the expected values with those numbers and the frequencies?

Complementation tests are performed in the (F1/F2/dominant/recessive/affects/does not affect) progenyof two (F1/F2/dominant/recessive/affects/does not affect) true-breeding mutants.If the two mutants are affected in different genes, the map distance between the twogenes (F1/F2/dominant/recessive/affects/does not affect) how often complementation is observed.

9 a,b,c

1) What is the pure-breeding (or true-breeding) strain or organism?

HOW DO I SOLVE THIS STEP BY STEP: Recent studies suggest that having the A blood type increases the risk of serious complications for patients suffering from COVID-19.  Sarah doesn't know her blood type, but she knows her father is type O and her mother is type AB. What is the probability, from 0 to 100 percent, that Sarah is blood type A? Enter a single whole number from 0 to 100.  If you think the answer is a fraction, then round to the nearest whole number.

How would I solve this?
