"for a certain breed of cat, short tails are dominant (t) and long tails are recessive (t). the punnett square below shows a cross between two parents. what is the phenotype ratio for this cross?
"

The correct answer is -

The phenotypic ratio for this cross is 3:1 ( short tail: long tail).

As per the information in the question, short tail of cat (depicted by T allele) is a dominant trait over long tails of cat (depicted by t allele), which is a recessive allele.

A dominant trait always masks the expression of recessive trait.

There can be two possible genotype for short tails, which are 'TT' and 'Tt'.

On the other hand, there is only one possible genotype for long tail, which is 'tt'.

Thus, from the given cross, we can conclude that the phenotypic ratio, representing the physical appearance of tail that is short and long tails is 3:1 (short tails: long tails).

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
