Answer:
a. 1/4 chance of occurring
b. 81/256
c. 3/4
d. 0.26
Explanation:
X-linked recessive inheritance is a pattern of inheritance in which a mutation in a gene on the X chromosome causes the phenotype to always get expressed in males (they have one X and one Y chromosome with mutation on the X) and in females who are homozygous for the gene mutation (mutation on both X chromosomes).
Indicating the mutation with h and the normal allele with H.Thus, if a heterozygous woman (XHXh) and an unaffected man (XHY). we have:
(XHXh) x (XHY)
XHXH XHXh XHY XhY
normal female normal male affected male
0.5 0.25 0.25
1/2 1/4 1/4
a. 1/4
b. Each unaffected offspring has 3/4 chance of occuring: four unffected - 3/4 x 3/4 x 3/4 x 3/4 = 81/256
c. 1/2 + 1/4 = 3/4
d. The probability of an unaffected offspring is 3/4. Here, the binomial expansion equation (where x = 2, n = 5, p = 1/4, and q = 3/4). The answer is 0.26, or 26%, of the time. probability of affected is 1/4. Thus, using this
P(x) = (⁵₂) pˣ (1 - p)ⁿ⁻ˣ =
= (⁵₂) (1/4)² (3/4)³ =
= 5!/3!2! (0.0625) (0.4219) =
= 10 (0.026)
= 0.26
B more ice on the earths surface. Greenhouse gases don’t tend to block the solar energy, but trap the energy that radiates from the earths surface. Dissolved CO2 becomes carbonic acid. More CO2 results in more carbonic acid. Methane is one of the greenhouse gases.
can you explain a little more please
The chemical formula of ammonium phosphate is (NH4)3PO4. There is 3*4=12 Hydrogen atom in one molecule ammonium phosphate. The total mass of one molecule is (14+4）*3+31+16*4=149. The mass of hydrogen atoms in one molecule is 3*4=12. So the mass percent of hydrogen is 12/149*100%=8.05%
