Question

Gene S controls the sharpness of spines in a type of cactus. Cacti with the dominant allele, S, have sharp spines, whereas homozygous recessive ss cacti have dull spines. At the same time, a second gene, N, determines whether or not cacti have spines. Homozygous recessive nn cacti have no spines at all. The relationship between genes S and N is an example of which of the following inheritance patterns:

Answer 1

Answer:

Autosomal recessive

Explanation:

both of the parents are carriers thus the characteristics are carried to the next generation but not wholly

Answer 2

The gene S and the gene N is an examples of  Autosomal recessive inheritance.

What do you mean by a Gene?

A gene may be defined as the basic unit of heredity that occupies a specific location on a chromosome.

Both genes S and N, when present in recessive forms show the character which is recessive. The heterozygous form of both genes are carriers. Gene S controls the trait sharpness of spines in cactus, while the gene N controls the presence of spines in a cactus.

Therefore, the gene S and the gene N is an examples of  Autosomal recessive inheritance.
