In garden peas, the yellow seed trait is dominant over green seeds. Also, the round seed trait is dominant over the wrinkled-see
Darina [25.2K]

Answer:

405 individuals will be yellow and round seeded.

Explanation:

<u>Available data:</u>

  • the yellow seed trait is dominant over green seeds
  • round seed trait is dominant over the wrinkled-seed trait
  • These genes are on separate chromosomes

Let´s name the seed color genes Y, and the seed shape gene R

  • Y is the dominant allele for seed color expressing yellow
  • y is the recessive allele for seed color expressing green
  • R is the dominant allele for seed shape expressing round
  • r is the recessive allele for seed shape expressing wrinkled

Cross: between two plants that are heterozygous for both traits

Parental)       Yy Rr            x       Yy Rr

Gametes) YR   yR   Yr   yr   YR   yR   Yr   yr

Punnet Square)   YR         yR         Yr         yr

                YR     YYRR     YyRR     YYRr    YyRr

                yR      YyRR      yyRR     YyRr     yyRr

                Yr       YYRr      YyRr      YYrr     Yyrr

                yr        YyRr       yyRr      Yyrr      yyrr

F1) 720 individuals

    9/16 yellow and round seeded individuals, Y-R-

    3/16 green and round seeded individuals, yyR-

    3/16 yellow and wrinkle seeded individuals, Y-rr

    1/16 green and wrinkle seeded individuals, yyrr

<em>Note: the "-" symbol in the phenotypes means that there it could be either a dominant or recessive allele. </em>

If 720 is the total number of individuals in the F1, then:

16 possible genotypes ---------- 100% of the progeny -------- 720 individuals

9 yellow and rounded----------- 56.25% ----------------------------405 individuals

3 green and rounded-------------18.75%------------------------------135 individuals

3 yellow and wrinkled-------------18.75%------------------------------135 individuals

1 green and wrinkled--------------6.25%-------------------------------45 individuals
