If pattern of inheritance is complete dominance what would you expect when a red and yellow fish were crossed

Biology
1 answer:
DIA [1.3K]4 years ago
7 0

In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.

Answer:

In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.

When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.

As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.

You cross purple-flowered and white-flowered pea plants, and all offspring are purple. how come? select one:
Vaselesa [24]
To solve this problem on genetic dominance, we will need a punnet square.

Let's let P represent purple-flowered and p represent white-flowered.

We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.

       <u>P</u>     <u>P</u>
p|    Pp   Pp

p |   Pp   Pp

As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.

Since each flower has a dominant and recessive allele, they are heterozygous.

Therefore, the solution to this problem is D.
