A tall pea plant results from a dominant tall allele while the short phenotype results from two recessive alleles. What is the frequency of short offspring (pp) when a tall pea plant with one tall allele (Pp) is cross-pollinated with a short pea plant (pp)?

Respuesta :

Answer:

0.5

Explanation:

Took the test xd ♡

The probability of short pea plant when a heterozygous parent cross with recessive is 0.5.

Law of dominance:

The cross between two pure parents results in the heterozygous dominant offspring in the first generation.

Here,

Parents are

P- dominant tall

p - recessive

Pp   x pp

The cross,

        p       p

P      Pp      Pp

p      pp      pp

From the cross it is clear that 50% of the offspring will have recessive alleles.

Therefore, the probability of short pea plant when a heterozygous parent cross with recessive is 0.5.
