Answer:
¼ or 25% will be dihybrid organisms, ¼ will be heterozygous at first locus and recessive homozygous at other locus , ¼ of them will be recessive homozygous at first locus and heterozygous at other locus, and ¼ of them will be homozygous recessive for alleles at two independent loci.
Explanation:
A dihybrid organism is one that is heterozygous at two different genetic loci. So if we name one gene with D and other gene with R, dihybrid organism will have genotype DdRr.
If we cross that organism with the one that is homozygous recessive for alleles at two independent loci ddrr:
P: DdRr x ddrr
Answer:
D
Explanation:
Cells are living things therefore, nonlivng objects do not have cells
Explanation:At each target effector, dual innervation determines activity. For example, the heart receives connections from both the sympathetic and parasympathetic divisions. One causes heart rate to increase, whereas the other causes heart rate to decrease.
Answer:
Stop habitat destruction
Explanation:
Cutting down and burning forests basically take away the shelter, hunting grounds, and overall habitat away from many species that use the trees as a form of shelter and protection. Removing their shelter, which could be their only form of protection causes many of these organisms to die, not to mention the plants that are necessary to keep the food chain balanced.
