The observed distribution of alleles into gametes is an illustration of Mendel’s law of segregation and independent assortment.
Mendel's law of independent assortment - the alleles a gamete receives get sorted into gametes independently of one another (one gene does not influence the allele received for another gene).
Mendel’s law of segregation - each gamete receives one gene copy selected randomly.
Answer:
Crossing over is somewhat randomly distributed over the length of the chromosome.
Two loci that are far apart are more likely to have a crossover between them than two loci that are close together.
Explanation:
Crossing over is the process of exchange of genetic material between two non-sister chromatids of homologous chromosomes. It occurs during pachytene of prophase I of meiosis I. The frequency of crossing over depends on distance between two genes present on same chromosomes. On the same chromosome, the distantly located genes are more likely to exhibit crossing over than the closely located genes.
Answer:
B) Oxygen and E) Carbon Dioxide
Explanation:
Cellular respiration has a general chemical equation as:
⇒ 
glucose + oxygen ⇒ carbon dioxide + water
Photosynthesis has a general chemical equation as:
⇒ 
carbon dioxide + water ⇒ glucose + oxygen
Reactants are on the left side of the equation while products are on the right. You can see that the products in cellular respiration are carbon dioxide and water, these also are the reactants in photosynthesis. So (B) Oxygen and (E) Carbon dioxide are the answers.
