Allele segregation and gamete formation one character in peas that mendel studied was yellow versus green seeds. a cross between a homozygous yellow line (gg) and a homozygous green line (gg) will result in f1 plants that are heterozygous (gg) for this trait and produce yellow seeds. cross between homozygous yellow and green pea plantswhen an f1 plant undergoes meiosis, what gamete types will it produce, and in what proportions?

Answer;

The probability of a gamete having one allele or the other is equal; thus 1/2 or 50 percent for either allele.

Explanation; According to Mendel's Law of Segregation states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization. In other words allele pairs segregate equally into gametes during meiosis, the process that occurs is sex cells where a single cell divides into four haploid cells. This means that a gamete will have only one allele of any given gene, and that the probability of a gamete having one allele or the other is equal and therefore the proportions will be ½, or 50%, for either allele).
