A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.

In this set of examples the answer is:

D) The lamprey does not have a vertical column

Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.

Cystic fibrosis is genetic, meaning it can be passed from parent to child. What type of mutation causes cystic fibrosis? somatic
Tresset [83]

Answer: Germline mutation

A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.

In Drosophila, straight wings are dominant to curved wings (c), smooth eyes are dominant to sparkling eyes (spa), and tan body i
77julia77 [94]

Answer:

\frac{1}{8}

Explanation:

Straight wings are dominant over curved wings

Let Straight wings : H

curved wings : t

smooth eyes are dominant to sparkling eyes

let smooth eyes = H

spark ling eyes = t

tan body is dominant to ebony body color.

Again; Let tan body color be H

Let ebony color be t

If flies that are heterozygous for all three traits are crossed;

we have HtHtHt × HtHtHt

Then the selected trihybrid traits for the cross will be (HHH,HHt, HtH, Htt, tHH, tHt, ttH, ttt)

We will realize that from the punnet square in the diagram below, the proportion of the offspring would you expect to be heterozygous for all three traits (i.e HtHtHt) is asterisk in the punnet square and will be \frac{8}{64}

= \frac{1}{8}
