Question

Raquel's mother is very tall and comes from a family in which almost everyone is above average in height. Raquel's father is quite short and comes from a family where almost everyone is below average in height. We would expect that Raquel will be of ______ height because the genes that affect height relate in a(n) ______ pattern.

Answer 1

Answer:

1. Average

2. Additive

Explanation:

Additive genes is a biological term that describes the condition at which genes in individuals specifically offspring are developed.

Additive genes are considered to developed when the dominant forms of both genes are present together and produce double effect.

In other words, additive genes is shown when two or more genes produce a single contribution to the final phenotype, such that, their combined effects equal the sum of their individual effects.

Hence, in this case, considering the combination of genes from someone whose family is above average in height with another person whose family is below average in height. Thus, it is expected that the offspring produce will be of AVERAGE HEIGHT, because the genes that affect height relate in an ADDITIVE pattern.
