Answer:
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
Explanation:
The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.
Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.
A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
They involve changes in energy. Hope this helps.
Answer:
C
Explanation:
I think it is C I hope this helps!
Correct answer: B) They produce most of the food that the ecosystem relies on
Decomposers are the organisms that break down the dead and decayed plants and animals. They also help in the breakdown of waste of other organism.
They are found to be very important for the ecosystem, if they were not present in the ecosystem them plant would not be able to get essential nutrients which are necessary for their growth. Because it the decomposers who help in the recycling of carbon and the nitrogen cycle.
Decomposers break down the dead and decayed material into simpler organic matter into carbon dioxide and nutrients.
Example: bacteria, fungi
Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
