(B) 25% GG, 50% Gg, and 25% gg
<u>Explanation:</u>
Given:
Green is dominant and is coded by G
Albino is recessive and is coded by g
Two corn plants that are heterozygous for color are crossed.
The heterozygous condition of the plant would be Gg.
The cross is shown in the table attached.
According to the punnett square drawn,
The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)
= 25% GG , 50% Gg , 25% gg
Phenotypic ratio = 3 : 1 ( green : albino)
= 75% green, 25% albino

6. The man is the father of the child with O blood group since it does not contribute O allele to the child and mother have BO alleles. The child will receive one O from mother since O is recessive allele it will be expressed in homozygous condition which is not possible with this cross.
7 The phenotype is half palamino and half cremello horses are produced . The genotype is HcHcr : HcrHcr (1:1 ratio)
Explanation:
Data given:
blood group of man = AB (genotype is AB)
blood Group of woman = B (genotype can be BB or BO
Child is O type = why
The cross shows
A B
B AB AB
O A0 BO
it is known that each parent contributes one of the alleles to their child in ABO blood system.
The father with AB group is able to pass either A or B allele to the child
Mother with BO could either pass B or O allele to the child. But since 0 is the recessive trait both parents must pass on O allele for the child to be O blood type.
Hence man with AB is not the biological father of the child.
7. data given:
Coat colour in horses depict phenomenon of codominance.
chestnut colour is Hc
cremello colour horse genotype = HcrHcr
plamino colour Hc Hcr
cross shows:
Hcr Hcr
Hc HcHcr HcHcr 2:2 cremello:plamino
Hcr HcrHcr HcrHcr genotype = 1:1 ratio
HcHcr : HcrHcr
Answer: a variable is something to be changed or tested
Explanation:
The variable is the thing in an experiment that is changed
<span>DNA is made up of nucleotides consisting of the sugar deoxyribose, a phosphate, and one of four nitrogenous bases.
