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
Hello!
The three kinds of cells in blood are white blood cells, red blood cells, and platelets.
Answer:
ample sunlight
steady nutrient supply
Explanation:
Neritic zine is the shallow end of deep water bodies.
This end receives stable temperatures of about 24 degrees celsius.
This area permits photosynthesis since light penetrates to the bottom, this is the reason why planktonic plants survive here.
The region has got steady salinity and because of its favourable nature, it has got many living organisms.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
