Question

on the right side of the screen, click on \genetic inheritance follows rules.\ read the paragraph, then click on the animation tab. go through the animation and answer the following questions:

1. write down the cross between two heterozygous (monohybrid) yellow pea plants in the punnett square below:

1. color the squares of the punnett square with the color of the offspring pea plants.

Explanation:

Step1: Define allele notation

Let $Y$ = dominant yellow allele, $y$ = recessive green allele. Heterozygous plants have genotype $Yy$.

Step2: Set up Punnett square axes

Place gametes of one parent on top, the other on the left. Each $Yy$ parent produces $Y$ and $y$ gametes.

Step3: Fill in Punnett square

Combine gametes from corresponding row and column.

	$Y$	$y$
$y$	$Yy$	$yy$

Answer:

The completed Punnett square for the cross $Yy \times Yy$ is:

	$Y$	$y$
$y$	$Yy$	$yy$

For question 16: Color the squares with $YY$ and $Yy$ yellow (yellow is dominant, so these genotypes produce yellow peas), and the square with $yy$ green (recessive homozygous genotype produces green peas).
