Question

a plant with red flowers (rr) is crossed with a plant having white flowers (rr) and all of the offspring in the first generation possess pink flowers (rr) - determine the type of genetical inheritance
simple dominance
co - dominance
incomplete dominance.
i do not know

Explanation:

Incomplete dominance is a form of inheritance where neither allele is completely dominant over the other. In this case, the red - flowered plant (RR) and white - flowered plant (rr) produce offspring with pink flowers (Rr). This is because the red allele (R) does not completely mask the white allele (r), resulting in an intermediate phenotype (pink). In simple dominance, one allele would completely mask the other (e.g., all offspring would be red if R was completely dominant). In co - dominance, both alleles would be expressed simultaneously (e.g., flowers with red and white patches).

Answer:

Incomplete dominance.
