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

Which best describes the process of peer review

777dan777 [17]

Answer:

Peer review refers to a process of evaluation which is designed to validate and assess the originality and quality of academic work.

Explanation:

In Academia, the revision of an academic work (e.g. a research article), or peer review, is fundamental to determine its originality and ensure good quality for publishing purposes.

This process starts when an author submits a research paper to a journal to publish it.
If all the requirements of the particular journal (each journal has different requirements and specifications) are met, the Editor sends it to experts on the particular area of study to assess it.
If all experts agree on the quality of the paper, they send a report back to the Editor, who decides whether the article should be rejected, revised, or accepted.
Authors then check the report and edit it appropriately (if accepted).
Whether if it is accepted or rejected, the Editor must communicate the decision to the authors of the paper.
