What does reproductive isolation within a species cause?A. A decrease in genetic drift
B. A decrease in gene flow
C. An increase in gene flow
D. an increase in genetic drift

Answers

Reproductive isolation within a species causes is an increase in gene flow. The correct option is C.

What is reproductive isolation?

Reproduction isolation is a mechanism constituted by some factors like behavior, physiological process, etc. by which the species does not reproduce with other species.

Gene flow is the flow of genes in forward generations, and reproduction isolation increase the gene flow within species.

Thus, option C. An increase in gene flow is correct.

3. Jenny crosses 2 hybrid pea plants. What is the probability that the offspring will beshort? Set-up and complete the punnett square below to solve this problem. (HINT: tt =
short, and TT & Tt = tall)

Answers

Answer:

A punnet square is a diagram which is made to illustrate the percentages of the traits that will be passed on from the parents to the offsprings.

If jenny crosses a heterogenous tall dominant pea plant with a short homozygous pea plant then 50 percent of the offsprings will be short.

If Jenny crosses a tall, dominant homozygous pea plant with a short homozygous pea plant then all of the offspring will be tall and heterogenous dominant

Answer:

Twenty five percent

Explanation:

Let us assume that the allele for tall pea plant be "T" and the allele for short pea plant be "t".

Also let us assume that "T" is dominant over "t"

A hybrid pea plant will have both the allele for tall and short plants.

Thus, genotype of hybrid pea plant would be "Tt"

Now if two hybrid pea plants are crossed, then following offspring are formed -

Tt * Tt

TT, Tt, Tt, tt

Thus, out of four only one offspring having "tt" genotype will produce short pea plants.

Thus, probability is equal to
