On a phylogenetic tree, which term refers to lineages that diverged from the same place?
Elden [556K]

Answer:

sister taxa

Explanation:

Groups departing from the same evolutionary node are called sister taxa and are evolutionarily closer to each other than groups departing from another node. Thus, we can say that the sister taxa are evolutionarily closer (related) to each other than to the taxa that did not diverge from the same place. Similarly we can say that taxa that did not diverge from the same place, cannot be called sister taxa and are distant evolutionary.

The frequency of carriers for a rare autosomal recessive genetic condition is 0.04 in a population. Assuming this population is
sertanlavr [38]

Answer:

E

Explanation:

Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others

the principle is defined by the equation

p² + 2pq + q² = 1

where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq

substitute the value into the expression

p² + 0.04  +  q² = 1;  The information is not enough to calculate either p or q going by the equation generated.
