The lamina propria is composed of loose connective tissue.
<span>Errors in genes that result in the production of defective proteins are called genetic mutations</span>
<span>The third option is correct, seed coat, stored food, embryo. The coat is what protects the inner parts from outside infuences, while the food is the nutrients that the seed uses when growing and developing. The embryo will eventually become the new plant that grows out of the seed. Seeds usually fall from things like pinecones on the ground near the original tree, which is why coniferous forests are usually very dense.</span>
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
