Question

1. Each bean represents a single allele. If the organisms in the population are diploid (they have two alleles for each gene), how many individuals are in the population?

1. Since each bean represents a single allele:

1. What allele does the black (or red) bean represent?

1. What allele does the brown (or white) bean represent?

1. What color combination of two beans represents a:

1. homozygous dominant individual?

1. Homozygous recessive individual?

1. Heterozygous individual?

What additional information do yall need?

Answer 1

Each bean represents a single allele. In the question the organisms in the population are diploid (they have two alleles for each gene). There are a total of 32 black and 48 brown beans. The total number of beans is 32+40= 80, i.e 80 alleles are present. Now since the organisms ar diploid so there are 80/2 = 40 individuals in the population.

According to the information given , the black (or red) bean represent the dominant allele, R.

The brown (or white) bean represent the recessive allele, r.

The color combination of two beans represents the colour of the dominant allele when present in homo or heterozygous forms. The recessive allele do not show any colour in presence of the dominant allele.

a:homozygous dominant individual - RR (black/red)
b.Homozygous recessive individual - rr (brown/white)
c. Heterozygous individual -Rr (black/red)
