Answer:
12 : 3 : 1
Explanation:
According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and 1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.
<em>Dihybrid cross for heterozygous summer squash:</em>
WG Wg wG wg
WG WWGG WWGg WwGG WwGg
Wg WWGg WWgg WwGg Wwgg
wG WwGG WwGg wwGG wwGg
wg WwGg Wwgg wwGg wwgg
Genotypes:
W-G- and W- gg = white = 12
ww G- = yellow = 3
ww gg = green = 1
The correct answer would be DNA Profiling. When Joe denied being the father of Lisa, Lisa's mom took Joe to the court to prove that he was Lisa's biological father. One way of proving that he's truly the biological father is by undergoing both DNA's into DNA profiling.
Answer:
Explanation:
Plants, algae, and some kinds of bacteria have the ability to photosynthesize. They have special organelles called chloroplasts.
These organelles are the site of <u>photosynthesis</u>. They contain green pigment known as chlorophyll which can capture sunlight. The light energy plus carbon dioxide and water are converted into glucose and oxygen.
The glucose becomes the organism's food and energy source, but the oxygen is just released as a waste product.
