In the Dobzhansky–Muller model, an ancestral population (aabb) splits into two lineages. Different mutations produce different n

ew alleles in each population (Aabb in one population, aaBb in the other). All of the following genotypes would be viable except:
1. aabb
2. Aabb
3. aaBB
4. AaBb
5. aaBb

All the genotype except aabb  would be viable.

Explanation:

The Dobzhansky model refers to the incompatibility of genes among species. The population of ancestral species was of the AABB genotype. But it is further divided into two populations.

One population involves a and A and the other has b and B. It has been found that the a and b are incompatible mutually. There is no presence of interaction between them in the actual species. So, the first genotype would not be viable in this model.

2. A certain recessive, lethal gene is carried on the X chromosome. (Lethal genes are those that result in death.) A man marries
son4ous [18]
The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)
| Xg | X
—————-
X | XXg | XX
—————-
Y | XgY | XY

Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
