Answer: Throwing back by a body or surface of light, heat, or sound without absorbing it.
Explanation:
Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.
Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.
Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.
Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.
"The tidal range was higher than normal due to the high tide which rose so high that it flooded the coast."
Answer:
Emergency Action Plan is necessary because- EAPs reduce the likelihood you will be sued if a student is injured. And EAPs let everyone on your staff know and practice what to do in case of an emergency.
Explanation:
Emergency Action Plan is a plan which addresses emergencies in a schools, workplace, or any institution. If any emergency situation like fire, floods occurs then EAP helps to lessen a trouble.
EAP is necessary because it makes the staff members aware about the preventive measures in an emergency situation. Apart from this, god forbid if any student is injured despite having an EAP, then chances are that the person in authority will not be sued mainly because the incident occurred despite having EAP and not without EAP.
Answer:
9:3:3:1
Explanation:
If alleles of two genes separate randomly during anaphase-I of meiosis, some new combinations of the alleles are formed in the gametes. A heterozygous genotype for two loci (let's support TtRr) produces a total of four types of gametes in 1:1:1:1 ratio (TR, Tr, tR, and tr). The random fusion of these gametes from two double heterozygous parents (TtRr x TtRr) gives a phenotype ratio of 9:3:3:1. Here, 9/16 F2 progeny exhibit dominant phenotype for both loci while 1/16 exhibits recessive phenotype for both the genes. Rest 3/16 and 3/16 F2 progeny express dominant trait for one gene and recessive for the other.
