You have a dog that drools (d). It turns out that this is a Mendelian trait and recessive in the population of dogs. You breed this drooling dog with another dog that does not drool and is heterozygous for the non-drooling trait. The possible allele combinations for the cross between the drooling dog and non-drooling dog are: Group of answer choices

Complete question:

You have a dog that drools (d). It turns out that this is a Mendelian trait and recessive in the population of dogs. You breed this drooling dog with another dog that does not drool and is heterozygous for the non-drooling trait. The possible allele combinations for the cross between the drooling dog and non-drooling dog are: Group of answer choices.

The possible allele combinations for the cross between the drooling dog and non-drooling dog are:

Only dd Dd and dd, but not DD Only Dd DD, Dd, and and dd, but not DD Drooling dog gametes → d, dNon-drooling dog gametes → D, dF1) 1/2 dd + 1/2 Dd (No DD)

Explanation:

Available data:

Autosomal diallelic geneThe D allele is dominant and expresses the non-drooling traitThe d allele is recessive and expresses the drooling traitCross: A dog that drools with a heterozygous dog that does not drool.

Parentals) dd    x    Dd

Gametes) d   d     D    d

Punnett square)   D     d

                       d   Dd   dd

                       d   Dd   dd

F1) 1/2 = 50% of the progeny is expected to be non-drooling dogs, Dd

     1/2 = 50% of the progeny is expected to be drooling dogs, dd.

Try and make the question more clear : )

Country b may have shorter life expectancies. country a has more literate people. country a has better health care system. apex
