Question

ANSWER ASAP PLEASE

A male pistol shrimp with protective eye tissue pockets mates with a female shrimp without protective eye tissue pockets. All of the offspring have eye tissue pockets. What is the most reasonable conclusion that can be made about the eye tissue pocket trait in pistol shrimp?
A: It is a recessive, autosomal trait.

B: It is a dominant, autosomal trait.

C: It is a trait that results from multiple alleles.

D: It is a trait that results from incomplete dominance.

Answer 1

B

Step-by-step explanation:

Answer 2

Option B, It is a dominant, autosomal trait.

Step-by-step explanation:

let us look at the cross as defined in this case

Let the trait "protective eye tissue pockets " be represented by A

and the trait "without protective eye tissue pockets" be represented by B

The genotype of male with protective eye tissue pockets will be "AA"

The genotype of female without protective eye tissue pockets will be "BB"

The following offsprings will be produced if a cross is carried out between the two parents "AA" and "BB"

AA X BB

AB, AB, AB, AB

Since all the offspring contains both A and B allele but only the traits associated with allele A i.e "protective eye tissue pockets" is expressed over and above the traits associated with allele B.

Thus allele A is a dominant autosomal trait
