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.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
