A true-breeding plant that produces yellow seeds is crossed with a true-breeding plant that produces green seeds. The F1 plants
nadya68 [22]

Answer:

The phenotypic ratio will be 3:1

Explanation:

As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.

The cross of true breeding plants as mentioned above is depicted as under:

Parents                             YY    x   yy

                                          /   \       /   \

F1 generation                Yy   Yy  Yy   Yy

So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.

Next, when these F1 plants will be crossed, the result will be as under:

F1 generation                    Yy   x    Yy

                                         /   \         /   \

F2 generation               YY   Yy   Yy   yy

The genotypic ratio of F2 generation is 1:2:1

The phenotypic ratio of F2 generation is 3:1

It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.

What is the difference between a lake and a pond? a. A pond is smaller in size and does not have a temperature gradient. b. A po
Ksju [112]

Answer:

I think the answer is A.

Explanation:

Ponds and lakes are both inland bodies of freshwater that contain living creatures. Lakes are normally much deeper than ponds and have a larger surface area. ... All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.

  The yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water gets deeper. You may have noticed this in summer while swimming.

What is the name of the tear collecting structure under the skin near the bridge of the nose?
Natali [406]
The name of the tear collecting structure under the skin near the bridge of the nose is the lacrimal sac. The lacrimal sac is part of the lacrimal drainage system or the lacrimal apparatus. The tears are produced in the lacrimal gland and will drain through a hole near the lower palpebral conjuntiva called the puncta which serves as the entrance in the lacrimal system. The tears will now enter the canalicula which serves as the passage way from the puncta to the lacrimal sac. Lastly, the tears in the lacrimal sac will drain to the nasolacrimal duct and to the nose. This also explains why we get runny nose when we are crying.
