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:

Available data:

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

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

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

nadya68 [22]

I think most scientists would not respect this researchers claim.
It doesn't seem like the researcher followed the steps of the scientific method.
1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.

Publishing his/her work would be the very last step after completing everything else.
