Ben Affleck has a cleft chin, but his ex-wife Jennifer Garner does not. Neither one of their two daughters (Violet and Seraphina

kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc

aleksandr82 [10.1K]

Answer:

The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.

Explanation:

Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.

Why do three species have similarities and differences in their body structure, and how can Xiao use the structures to determine

Varvara68 [4.7K]

Answer: Xiao can use these structures to create a similarity matrix that enables to differentiate between synapomorphies and homoplasies .

Explanation: A synapomorphy is a trait that has been inherited from the same ancestor, this trait enables to establish a relation of homology between two or more species; while a homoplasy is an analog structure that doesn't have homology.

at which location does gravity play a role in moving tectonic plates? at the edge of the plates. in the core. in the mantle. in

yulyashka [42]

Answer:

B. At the edge of the plates

Explanation:

Gravity is the principal driving force of plate tectonics (second one is convection). It causes different density plates to move on the Earth's surface. However, when a denser plate coincides the less denser plate, the high density plate subducts below the lesser density plate. The process, therefore, is called subduction. During this collision of plates, shearing resistance increases and all pressures come at the edge of the plate. The process continues and the lithosphere drags the rest of the plate. The portion of plate below the less denser plate then reaches the mantle. Here, the edge of plate is destroyed due to high temperature of mantle as well as pressure.
