Theodor Schwann and Matthias Schleiden were major contributors to the Cell Theory as we know it. In 1839 Schwann published a boo

k including a summary of his observations into three conclusions about cells: 1. The cell is the unit of structure, physiology, and organization in living things. 2. The cell retains a dual existence as a distinct entity and a building block in the construction of organisms. 3. Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation). Which one of Schwann's statements is no longer accepted as truth? A) Cells are found in both living and nonliving entities. Eliminate B) Cells are distinct identities, not just building blocks. C) Cells form via free cell formation from existing cells only. D) Cells come from free cell formation similar to spontaneous generation.

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
