In garden peas, long stems are dominant to short stems, and yellow seeds are dominants to green seeds, too long/yellow pea plant
Lera25 [3.4K]

Answer:

A) 300

B) 3:1

C) 9 long yellow : 3 long green : 3 short yellow : 1 short green

Explanation:

Long stems (L_) are dominant to short stems (ll)

Yellow seeds (Y_) are dominant to green seeds (yy)

We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.

C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:

  • 9/16 L_Y_ (Long, yellow)
  • 3/16 L_yy (Long, green)
  • 3/16 llY_ (short, yellow)
  • 1/16 llyy (short, green)

A) 3/16 × 1600 = 300 plants will be long and green.

B)

9/16 + 3/16 = 12/16= 3/4 plants will be yellow;

3/16 + 1/16 = 4/16= 1/4 plants will be green.

The ratio will be 3 yellow : 1 green
