The answer is Both features have a recessive phenotype in these offspring.

An individual's phenotype is defined by their genotype and expressed genes, as well as apparent traits such as hair colour or type, eye colour, body shape, and height. It is determined by the genotype, but it is also modified by environmental circumstances.

What is genotype?

  • The genotype of a person can reveal their genetic makeup.
  • It determines which qualities will be expressed.
  • Organisms with similar appearances do not share the same genotype.
  • Biological tests can be used to determine a person's genotype.

asambeis [7]

Answer:

1/4.

Explanation:

The Mendel is known as father of genetics. He explained the concept of dominance, law of segregation and law of independent assortment while working on the pea plant.

The cross between the heterozygous seed color (Ss × Ss), result in the 3/4 dominant phenotype ( SS, Ss and Ss ) and 1/4 recessive phenotype with alleles ss.

Ss   ×   Ss

progeny obtained are SS, Ss, Ss and ss.

Thus, the correct answer is option (3).
