Answer:d
Explanation: I'm smart lol trust me
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
'colored feathers that camouflage birds from predators are found in the majority of the current bird population' would be correct since that would only focus on one species instead of many, natural selection includes all species, not just one.
Answer:
There are two kinds of cellular communication: communication between cells is called intercellular signaling, and communication within a cell is called intracellular signaling.
