Answer:
Parent 1: G gametes
Parent 2: g gametes
Explanation:
This question involves a single gene coding for seed color in pea plants. The allele for green seeds (G) is dominant over the allele for yellow seeds (g). This means that a plant that is heterozygous (Gg) will possess green seeds.
If two parents are about to cross in such a way that Parent 1 is homo-zygous for green seeds i.e. GG, while Parent 2 is homo-zygous for yellow seeds i.e. gg.
- Parent 1 (GG) will produce only "G" gametes
- Parent 2 (gg) will produce only "g" gametes
The debate<span> you refer to is about the ethics of embryonic </span>stem cell research<span>. And, of course, since ethics is involved many would tend to oppose further research on this area because to them it violates and does not respect life. Hope this helps. Have a nice day.</span>
Answer:
The rate would increase.
Explanation:
Activation energy is the energy needed for a chemical reaction to start while the rate of reaction is how a reactant turns into the product. Catalysts are used to speeden up the rate of a chemical reaction.
The catalyst do this by lowering the activation energy needed for the reaction to occur, leading to the increase in the rate at which the same reaction occurs. It should be noted that a catalyst is not a reactant, neither does it get used up in the chemical reaction. It just provides an alternative energy pathway with a reduced activation energy, hereby, helping the reaction to proceed faster than it would without the catalyst.
Cross of true breeding dominant and recessive tomato plants will have:
Phenotype ratio in F1 generation is 4:0
genotype ratio in F1 generation is 4:0.
Explanation:
Data given:
Tall vine = dominant TT
dwarf vine = recessive tt
red fruit dominant RR
yellow fruit recessive rr
true breeding tall tomato plant bearing red fruit is TTRR
true breeding dwarf tomato plant bearing yellow fruit = ttrr
the cross is shown in punnet square:
TR TR
tr TtRr TtRr
tr TtRr TtRr
the phenotype ratio- 4:0
the genotype ratio - 4:0
The phenotype is tall vine with red fruit
Genotype is all the progeny are heterozygous dominant.
