Answer:
Rounding down to the nearest whole number, 5 Kittens will be white.
Explanation:
<u>Available data:</u>
- grey color (G) is dominant
- white color (g) is recessive
- white female, gg
- heterozygous male, Gg
- 9 Kittens
Cross:
Parental) Gg x gg
Phenotype) Grey White
Gametes) G g g g
Punnet square)
G g
g Gg gg
g Gg gg
F1) Genotypes:
1/2 = 50% will be Gg
1/2 = 50% will be gg
Phenotypes:
1/2 = 50% will be Grey (Gg)
1/2 = 50% will be white (gg)
To calculate the number of kittens that will be white, we need to consider the proportions of cats that will be white in the F1 and that the total number of kittens is 9. So
100% of the progeny ------------------------------- 9 kittens
50% of the progeny----------------------------------X = (50 x 9)/100 = 4.5 kittens ≅ 5 Kittens
A cat can not have 4.5 kittens, so we must round down to the nearest whole number. 4.5 ≅ 5 Kittens
