100% because the genotypes for the girls are FF and the man's are ff meaning all children will be Ff with the freckles trait
Answer:
See the answer below
Explanation:
The question that can be answered with the F2 cross would be <u>if the yellow flower color is dominant over the red flower color in the species</u>. In other words, <u>whether the inheritance of flower color follows a simple Mendelian inheritance or otherwise can be answered.</u>
<em>Assuming that the inheritance of the flower color follows the Mendelian pattern, the red flower trait would re-emerge among the F2 offspring and the ratio of yellow to red flower offspring would approximately be equal to</em><em> 3:1.</em><em> Otherwise, a more complex pattern of inheritance would be involved.</em>

Since the cancer cells grow and multiply much more quickly than most cells in our body. It is given with the curative intent or it may prolong life on to reduce symptoms in the cancer patients.
Answer:
As mammals grow, they stop producing lactase.
Explanation:
Mammals consume their mother's milk during the first stage of life. Milk has a sugar called lactose. Lactose is a disaccharide formed by the union of one molecule of glucose and another of galactose. To absorb it our digestive system releases an enzyme (lactase) that breaks the union between galactose and glucose. As mammals grow, they stop producing this enzyme, which makes lactose indigestible. As a result, ingesting milk may cause diarrhea, gas and bloating.
