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 Average Cow
of milk per year, that's nearly 2,500 gallons a year! On a daily basis, most cows average about 70 lbs. of milk per day, or about 8 gallons per day. 8 gallons is about 128 glasses of milk per day.
Answer:
Explanation:
During replication a new strand of DNA is synthesized when the other strand is a template to guide the process. Every time the order of the bases in preserved so that DNA can be accurately replicated over and over with identical genetic information.
Answer:
Science uses fossil evidence to support evolution theories because you can link similar fossils among creatures from millions of years ago, to the living creatures of today.
