Consider the given cross between two cats.The probability of the offspring cats produced by this cross would be:
Correct answer: C. 50% black long-haired and 50% black short-haired
- A. 100% black long-haired
- B. 75% black long-haired and 25% black short-haired
- C. 50% black long-haired and 50% black short-haired
- D. 25% black long-haired and 75% black short-haired
Explanation
The correct answer is 50% black long-haired and 50% black short-haired, which indicates that the genetic cross involves one parent being homozygous for one trait (hair length) and heterozygous for the other. Each trait has a 50% chance of being passed on to the offspring. Other options suggest ratios that imply different genetic combinations not supported by the stated problem.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
