Question 9 (1 point)
In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?

Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3

Question 9 1 Point In Peas Long Stem A Is Dominant Over Short Stem A A Heterozygous Long Stem Plant Aa Is Crossed With A Homozygous Short Stemmed Plant Aa Which class=

Sagot :

Answer:

Box 1 and 3

Explanation:

Box 1 represents the allele Aa

Box 2 represents the allele aa

Box 3 represents the allele Aa

Box 4 represents the allele aa

So the answer is Box 1 and 3 because Aa is a heterozygous allele and aa is a homo-zygous allele.

A cross among individuals with contrasting variations at one locus for the attribute is called a monohybrid cross. Each parent provides one type of allele or a trait to their offspring.

Monohybrid cross can be shown using the Punnett square, to determine the probability of a progeny expressing that genotype.

The correct answer is :

Option C. Box 1 and box 3

The reason for the answer is:

1. Box 1 will produce offspring with genotype: Aa

 

2. Box 2 will produce offspring with genotype: aa

 

3. Box 3 will produce offspring with genotype: Aa

 

4. Box 4 will produce offspring with genotype: aa

Therefore, Box 1 and Box 3 represents heterozygous alleles, whereas box 2 and box 4 represents purebred alleles.
