Answer:
Let "L" be the dominant allele for little finger shape and "l" be the recessive allele for the same.
It is given that a person is homozygous dominant for blood group B and little finger shape. Hence, the genotype would be 
<em>LL</em>
The other person is heterozygous for blood group A and homozygous recessive for little finger shape. Hence, the genotype would be 
The type of gametes formed by the first parent would be 
<em> </em>only.
The type of gametes formed by second parent would be 
and <em>il.</em>
The cross is shown in the attached figure.
According to the cross, we get two phenotype:
- offspring with blood group AB and dominant little finger shape, and
- offspring with blood group group B and dominant little finger shape.
- They are present in 4 : 4 = 1 : 1
According to the cross, we get two genotype:
- They are also present in 4 : 4 = 1 : 1.
Its our warm bloodlessness we stay at one temp because our blood has to be that warm at all times
<span>Embryonic tissues or germ layers develop during the gastrulation stage.</span> <span>Gastrulation is a process in embryonic development during which the single-layered blastula is reorganized into a three-layered(or two-layered) structure called the gastrula. <span>Two primary germ layers(embryonic tissues) are an inner layer-endoderm and an outer layer-ectoderm. Endoderm and ectoderm interact and produce a third layer-mesoderm. Gastrulation is followed by organogenesis, three germ layers will give rise to specific tissue and organ.For example, ectoderm gives rise to epidermis and nervous system, endoderm to the digestive system and mesoderm to muscles, bones…</span></span>

Symbiosis is the relationship of 2 organisms. The 3 major types are commensalism, mutalism, and parasitism. Hope that this helps!
