Amale rabbit with the genotype bbee is crosses with a female rabbit with the genotype bbee the square is set up below. fill it out and determine the phenotypes and proportions in the offspring.

Half i.e 8 progenies will have black hair and long ears.

Half i.e 8 progenies will have black hair and floppy ears.

No progeny will have any brown hair and long ears.

No progeny will have brown hair and floppy ears.

Explanation:

The genes mentioned here B and E are the genes for fur colour and ear length respectively.

The dominant character B represents black hair color whereas the recessive allele b represents brown hair colour.

The dominant character E represents long ears whereas the recessive allele e represents floppy ears. Both the genes are completely dominant over their recessive alleles.

Here in the question, the genotype of the two parents are BBee and bbEe respectively.

So gametes from 1st parents are Be only.

Gametes from 2nd parent are bE and be.

So crossing them, the genotypic ratio comes as

BbEe : Bbee = 1:1.

So half of the progenies will have black hair and long ears and half will have black fur and floppy ears.
