Question
Can you solve a and b
[Note - use the rules of probability (and show your work) instead of huge Punnett squares] 4. A black rabbit is crossed with a brown rabbit. All of the babies in the F1 generation have black fur. When one of these babies is crossed with a brown rabbit, approximately 50% of the babies in the F2 generation are black and 50% are brown. a) b) What conclusions can be drawn about fur color in rabbits? Create a labelled Punnett square to show the creation of the F2 generation described above

Answer #1

Answer:

a). Based on the information, black (B) is dominant over brown (b).

The second cross to produce F2 is testcross

b).

Black (BB) x Brown (bb)---Parents

Bb (black)---------------------F1

Bb (F1) x bb (brown)---Testcross

F2

b

B

Bb (balck)-50%

b

bb (brown)-50%

    On the island of Notion, in the Factotum Archipelago, there lives a population of pencil bears. A portion of these bears have silky fur, and as a result, are much better surfers. The texture of the fur is determined by a single autosomal locus with two alleles: S (trait allele) and s (wild type allele). In a recent study, researched collected the values in the following table: Table 1. Counts of Pencil Bear fur style by genotype Phenotype Genotype Silky...
