Answer:
If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.
Explanation:
When a disorder or disease is recessive it requires<u> two alleles with the disorder to manifest</u>. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.
<u>Parents
</u>
♂ Dd
♀ Dd
Both without disorder but presenting the altered gene, which makes them carriers.
<em>Alleles D d
</em>
<em>D DD Dd
</em>
<em>d Dd dd</em>
The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.
In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.
Answer:
I don't know where you got the four answers from, but I just spent 5 minutes trying to find the answer. The energy is suppose to go from the chloroplast to the mitochondria, to mix with carbon to become glucose. It is, however, called the Calvin Cycle. My apologies if I'm just misinterpreting the question, but this is the answer I found.

that one is the top one. whats the first drop down
Pretty sure the answer is Sugar, Correct me if I'm wrong
Answer: anaphase I
Explanation: Separation of homologous chromosomes occurs after the formation of tetrads, during anaphase I of meiosis. All of the other answers are processes that occur during both meiosis and mitosis. Both divisions require the condensation of chromosomes and eventual cytokinesis to produce daughter cells.
