From the cross aaxaa the possibility of producing a homozygous dominant offspring is

The probability of producing a  dominant homozygous offspring is 25% or 1/4.

Explanation: From the cross Aa x Aa is obtained offspring with genotypes: 1) dominant homozygous  (AA, 25% or 1/4), 2) Heterozygous (Aa, 50% or 1/2) and 3) Recessive homozygous (aa, 25% or 1/4).

the correct answer in apex is tissue development, i know because i just had this question

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
