Let the allele for white fruit be represented by w and that for yellow by W. What kind of gametes as to fruit color will be produced by plants of the genotypes: ww, Ww, and WW?

A. All white fruit
B. All yellow fruit
C. Half white and half yellow fruit
D. Three-quarters white and one-quarter yellow fruit

Answer :

Final answer:

The genotypes ww, ww, and ww will produce gametes for yellow, white, and both white and yellow fruits respectively. However, without the full context or correct allele representation, it is not possible to map these genotypes to the provided answer choices exactly.

Explanation:

The question pertains to Mendelian genetics and specifically addresses gamete formation with respect to different genotypes for fruit color in plants. Based on the alleles given (w for white and w for yellow), each genotype would produce the following types of gametes concerning fruit color:

  • ww: All gametes produced by this homozygous recessive plant will carry the allele for yellow fruit.
  • ww: All gametes produced by this homozygous dominant plant will carry the allele for white fruit.
  • ww: With this heterozygous plant, gametes will carry both the white and yellow alleles in a 1:1 ratio, meaning 50% white and 50% yellow.

So, the correct answer to the question is:

  • A. All white fruit
  • B. All yellow fruit
  • C. Half white and half yellow fruit
  • D. Three-quarters white and one-quarter yellow fruit

However, the correct answer option is not explicitly mentioned since the plant genotypes provided do not match with any of the answer choices exactly. Therefore, the student should review the given genotypes and the associated allele representation for correctness before proceeding with the gamete analysis.
