In Datura, spiny bolls dominate smooth bolls. What offspring can be expected from spiny heterozygotes and homozygotes? Describe all genotypes and phenyotypes.

Let’s designate the gene that causes the presence of spines on the dope pod as C, then the gene, in the homozygous state, which causes the dope pod without spines will be c.

The spiny bolls of a heterozygous, according to the condition of the problem, dope will be due to the Cc genotype. Such a plant will produce C and c germ cells.

Homozygous datura can be either CC or cc. Let’s consider both options.

Homozygous Datura – cc (smooth capsules). It produces the same type of sex cells with.

The offspring obtained from the described plants will look like this: 50% of Datura will have spiny bolls (Cc), 50% will have smooth bolls (cc).

Homozygous Datura – SS (boxes with spines). It will produce the same type of germ cells C. The offspring will look like this: 100% of the bolls will have spines, while half of the plants will be Cc (heterozygotes), the other half will be CC (homozygous plants).
