In a certain plant, red flowers are dominant over white flowers.

A plant heterozygous for red flowers and a plant with white flowers are crossed.

Which of the following is the expected proportion of phenotypes in the next generation?

2 red, 2 white.

In this cross, the plant heterozygous for red flowers has the genotype Rr (where R represents the dominant red allele and r represents the recessive white allele), while the plant with white flowers has the genotype rr.

The possible offspring from this cross would have the genotypes Rr (red), Rr (red), rr (white), and rr (white), resulting in a 1:1 ratio of red to white flowers.

A gene is the basic physical and functional unit of heredity and it is the DNA that make up genes. Enzymes are biological catalysts that speed up metabolic and cellular reactions in our bodies. Hormones are responsible for controlling the action of certain cells or organs in our bodies. Blood types are of four types, A, B, AB, and O.

The complimentary base pairing of DNA states that A pairs with T while C pairs with G. From the give sequence, the complimentary DNA strand will be 3’ TCGATCGCA 5’

Electrophoresis is a lab method that is commonly used to separate charge molecules based on their size. Some of the charged molecules include DNA, RNA, and proteins.
