Question

(ONE QUESTION) (PLEASE ANSWER IF YOU CAN)

The picture shows the dihybrid cross of 2 guinea pigs.
1. What is the genotype of the parents?
2. What is the phenotype of the parents?
3. What is the genotype of their baby guinea pig (in the empty box)?

a. BbRr - black rough fur - bbRR
b. BrRr - black smooth fur - gray wavy fur
c. BbRr - black rough fur - black rough fur
d. BrRr - white smooth fur - BrBr

Answer 1

1. Genotype of the parents are BbRr black rough fur-

2. Phenotype of the parents are BbRr-black rough fur-bbRR

3. genotype of their baby guinea pig is bbRR

Step-by-step explanation:

The genotype is the set of genes determining the particular trait in an organism. Here BbRr is the genotype of parents determined from F1 generation.

The Phenotype is the physical appearance of chraracter in an individual as in the given example the parents would have been heterozygous dominant or recessive traits.

The genotype of the baby is being determined after crossing the particular alleles of the parents.

Answer 2

Genotype of parents is BbRr.

Phenotype of parents is black rough furred.

The genotype of the missing baby is bbRR.

Option A.

Step-by-step explanation:

Genotype of an organism is the genetic setup or an organism related to a particular character which reveals what is the hybridization of the organism. Whereas phenotype of an organism is the overall look or physical approach of the organism which is result of the expression of genes present in the organism.

Here we can see that the genetic setup of the parents is BbRr which is heterozygous black rough furred.

So the types gametes produced by the parents = BR, Br, bR, and br.

So as per statistics, 16 different types or progenies can be born which are given in the punnett square.

The genotype of the missing baby is bbRR.
