Question

scientists attempted to produce a hybrid plant that was the result of the fertilization of gametes between one plant with a diploid number of 24 and another with a diploid number of 20. how many chromosomes would a zygote from this fertilization event have? 20 chromosomes 24 chromosomes 44 chromosomes 22 chromosomes

Explanation:

Step1: Find haploid number of first plant

Gametes are haploid. For a plant with diploid number 24, haploid number is $\frac{24}{2}=12$.

Step2: Find haploid number of second plant

For a plant with diploid number 20, haploid number is $\frac{20}{2}=10$.

Step3: Calculate zygote chromosome number

A zygote is formed by fusion of gametes. Chromosome number in zygote = 12 + 10=22.

Answer:

22 chromosomes
