Cats have a gene that codes for the colour of their fur.Suppose that a certain breed of cat can have black, gray, or white fur.

Black fur is dominant, white fur is recessive, and gray fur is intermediate (i.e., cats with gray fur possess one allele for black fur and one for white fur).If agray a cat and a white cat have kittens,what phenotype could the kitten exhibit?

<h2>Phenotype of the kitten exhibit</h2>

Explanation:

  • By the help of Punnet square  Let's call black 'B' and white 'b'
  • Being intermediate, gray cats will have the alleles 'Bb'
  • Being recessive, white cats will have the alleles 'bb'
  • Cross between black and white colour: B X b=Bb            
  •  punnet square:                

                       B     b  

                   b  Bb   bb

                   b   Bb   bb

  • Bb = Gray
  • bb = White
  • So the cats can have gray or white fur
  • hence, the right answer is "gray or white fur".

. The mean grain yield of an open pollinated rye breeding population is determined to be 72 bushels/acre. Your goal is to improv
Free_Kalibri [48]

Answer:

a) the selection intensity is 21bushels/acre

b) the response to selection is 12bushels/acre

c) The heritability is 0.57 (two decimal places)

Explanation:

Given:

mean grain yield population=72bushels/acre

mean grain yield selected individuals=93bushels/acre

mean grain yield new population=84busgels/acre

a) The selection intensity is given by:

SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre

b) The response to selection is:

RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre

c) The heritability of grain yield is:

H=RS/SI=12/21=0.57

The oxygen molecule on water has a partial negative charge? True or false
padilas [110]
The answer is true. In a water molecule, oxygen attracts more electrons than hydrogen. Because of this unequal balance, water has a partial negative charge by the oxygen atom and vise versa by the hydrogen atom. Hope this helps.
