In guinea pigs, rough coat (R) is dominant over smooth coat (r). A rough-coated guinea pig is bred to a smooth one, giving eight rough and seven smooth progeny in the F1. (Note that the experimental data may not be perfect as the expected data) What follows is a fill in the blank question with 4 blanks. What are the genotypes of the parents and their offspring? Rough-coat Parent Genotype: Smooth-coat Parent Genotype: F1 Rough-Coat Offspring Genotype: F1 Smooth-Coat Offspring Genotype:

In guinea pigs, rough coat (R) is dominant over smooth coat (r). A rough-coated guinea pig is bred to a smooth one, giving 8 rough and 7 smooth progeny in the F1 generation. A) What are the genotypes of the parents and their offspring? B) If one of the rough F1 animals is mated to its rough parent, what progeny would you expect?

00:02 So here we are going to see a question which says in guena pig's rough coat is dominant over the smooth coat.
00:09 So, so the rough coat is dominant over the smooth coat.
00:18 A rough coat guenna pig is bred to a smooth one giving eight rough and seven smooth progeny in the f1 generation.
00:25 What follows is a, what are the genotypes of the parents and their offspring? so, here moving with the solution we see that the dominant genes are dominant genes are those genes that usually mask the effect of that usually mask the effect of that usually mask the effect of recessive genes.
01:24 Excessive or less dominant gene.
01:28 So moving ahead with the explanation of the answer, we see that when a rough coated, a rough coated, guenia pig is bred with bread, bread, smooth coated one, smooth, smooth, coated one.
02:13 The probability of getting the probability of getting, probability of getting, probability of getting both types of figs is almost same.
03:00 The genotype are, the genocytes are, here we are going to create a cross...
