Question

a homozygous green betta fish (b₁b₁) is crossed with a homozygous steel blue betta fish (b₂b₂) to produce the f₁ generation. the offspring produced in the f₁ generation are heterozygous (b₁b₂) with a royal blue color. what type of non - mendelian inheritance pattern is represented by the betta fish?

codominance

multiple allele traits

sex - linked inheritance

incomplete dominance

Explanation:

In incomplete dominance, the heterozygous offspring show an intermediate phenotype between the two homozygous parents. Here, the green and steel - blue parents produce heterozygous offspring with a royal blue color (an intermediate color), which is characteristic of incomplete dominance. In codominance, both alleles are fully expressed simultaneously. Multiple allele traits involve more than two alleles for a gene. Sex - linked inheritance is related to genes on sex chromosomes.

Answer:

incomplete dominance
