B. Subgroups
<span>When constructing a dichotomous key, the first step is to look at the group of objects or organisms and separate them into two groups based on a single distinguishing characteristic. Then continue to separate each of the groups until each object has its own separate set of characteristics.</span>
myocites (could be wrong )
Answer:
Red blood cells
Explanation:
They transport Oxygen throughout the body.
The frequencies of R is 0.75 and the frequencies for R' is 0.25.
Explanation:
Data given:
Genotype frequency of incomplete dominance on flower colour of snapdragon:
RR = red 0.5625
RR' = Pink 0.375
R'R' = 0.0625
frequency of R and R'=?
According to Hardy-Weinberg equilibrium the genetic variation in a given population is constant from one generation to other if no factors causing evolution or genetic drift is there. So,
+
+ 2pq = 1
The p represents = homozygous dominant RR
q represents = homozygous recessive R'R'
2pq = frequency of heterpzygous genotype RR'
= 0.5625
p = 0.75 (frequency of R)
= 0.0625
q = 0.25 (Frequency of R')
Their sum is 1 as according to Hardy Weinberg condition:
p+q = 1
Pneumonia is a leading cause of death.
