Meiosis is different from the process shown because, during meiosis, A) chromosomes are not replicated. B) two gametes are made for every original cell. C) four gametes are produced for every original cell. D) four somatic cells are produced for every original cell. Two heterozygous purple-flowering pea plants are crossed. If purple is dominant over white, what are the expected phenotypic results? A) 100% purple. B) 75% purple, 25% white. C) 50% purple, 50% white. Eliminate D) 25% purple, 75% white. What is an explanation of why producers are always found at the

The answer for number 1 is letter B. four gametes are made for every original cell. This happens in the process of meiosis from the parental cells and then divides them leaving nucleus to attach in each two daughter cells carrying four gametes in all. The answer for number 2 is letter B. 75% purple and 25% white. When you use punnett square, if "A" is the dominant trait which is purple and "a" is white then you will get 1 "aa", 2 "Aa", and 1 "AA" making the traits to be 75% purple and 25% white.

The correct answer is C) four gametes are produced for every original cell. Meiosis is a type of cell division (reduction division) for production of gamets-sex cells, or sperm and eggs. During this process, the cell divides twice(meiosis I and meiosis II) to produce four cells (gametes) containing half the original amount of genetic information (from a diploid 2n set of chromosomes to haploid n). When two gametes unite during fertilization, each contributes its haploid set of chromosomes to the new individual, restoring the diploid number.  



The correct answer is B. 75% purple and 25% white.  
If A is an allele of the gene for purple, (dominant) color and a is an allele for white (recessive) color, then:
Aa is heterozygote genotype (purple), aa recessive homozygote (white), AA dominant homozygote (purple).
If Aa  x  Aa
F1: AA  Aa  Aa  aa
AA Aa and Aa will give purple color (75%)
Aa will give white color (25%)
