Which of the following could be considered the most recent common ancestor of living tetrapods? a) a sturdy-finned, shallow-wate

tensa zangetsu [6.8K]

Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.

Explanation:

An ancestor - An earlier type of a species at any distant time — a progenitor.

A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.

The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.

Please help!!!! very confused pt 2

Schach [20]

Answer:

If the genotype of the parents are Iᵃi and Iᵇi, then four type of offspring will be produced.The genotype of the offspring are, IᵃIᵇ, Iᵃi,Iᵇi, and ii.

Explanation:

IᵃIᵇ = As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

Iᵃi= In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

Iᵇi= In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

ii= This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
