LOCAL ENVIRONMENT ISSUE:
People dump a lot of trash in the sea, and the sea creatures living there goes through a lot of trouble to live with all the muck getting in them. Of course, don't write it like that in your assignment - you'll get told off for the straight forwardness.

Answer:

<em>Plants </em>are generally considered the best indicators of the level of succession in an ecosystem. Explain how you got your answer.

Explanation:

Plants are generally forms the basis of life in any environment, other organism strictly depends for survival and continuation of life as they are the only autotrophs in the food chain. The best indicator of the level of succession in an ecosystem remains the plant

g a true breeding pea plant with round and green seeds was crossed to a true-breeding pea plant with wrinkled and yellow seeds.
Sveta_85 [38]

Answer:

The probability of producing a round and green plant from this cross is 3/16

Explanation:

This question involves two distinct genes coding for seed shape and seed colour. In the seed shape gene, allele for round seeds (R) is dominant over allele for wrinked seeds (r), while in the seed colour gene, allele for yellow seed (Y) is dominant over allele for green seeds (y).

A truebreeding plant means that the plant possesses homozygous genotype. Hence, a truebreeding pea plant with round and green seeds will have genotype: RRyy while true-breeding pea plant with wrinkled and yellow seeds will have genotype: rrYY. These two parents will produce F1 offsprings with genotype: RrYy (heterozygous).

When the F1 offsprings are self-crossed (RrYy × RrYy), the following allelic combinations of gametes will be produced by each F1 parent: RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible F2 offsprings with a phenotypic ratio 9:3:3:1 will be produced

9- Round yellow offsprings (R_Y_)

3- Round green offsprings (R_yy)

3- Wrinkled yellow offsprings (rrY_)

1- Wrinkled green offsprings (rryy)
