ecies? When Charles Darwin set sail on the HMS Beagle, what did he and most of his contemporary scientists think about the origin of species? Most scientists, including Darwin, thought each species was specially created by God in its present form and did not change over time. Most scientists thought species were the product of natural processes, but Darwin had different ideas. Most scientists, including Darwin, thought species were the product of natural processes and changed over time. Most scientists thought species had been created in their current forms and were unchangeable, but Darwin believed in a natural origin of spe

In pea plants, the allele for round seeds is dominant to the allele for wrinkled seeds. If a plant that is heterozygous for seed
Harman [31]

Answer:

50%

Explanation:

According to this question involving a gene coding for seed shape in pea plant, the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). This means that a heterozygous pea plant (Rr) will have a round seed shape.

If a plant that is heterozygous for seed type (Rr) is crossed with one that has only homzygous wrinkled seeds (rr), the following gametes will be produced by each parent plant:

Rr - R and r

rr - r and r

Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:

Rr, Rr, rr and rr

Rr = round seed offsprings

rr = wrinkled seed offsprings

Since 1 out of 2 offsprings has wrinkled seeds, 1/2 × 100 = 50% is the percentage of offsprings expected to have wrinkled seeds.

In mice, black fur is dominant to grey fur. If you cross a BB male with a Bb female, what are the possible genotypes and phenoty
coldgirl [10]

Answer:

50% BB (black), and 50% Bb (black)

Explanation:

When you make the punnet square, you will get two BB, and two Bb. That will show you that the outcome of all the offspring will be black. There is 0% chance there will be a grey mouse because it is the recessive gene.
