P - dominant allele for inflated pods p - recessive allele for inflated pods PP - homozygote with inflated pods Pp - heterozygote with inflated pods pp - homozygote with inflated pods
S - dominant allele for round seeds s - recessive allele for wrinkled seeds SS - homozygote with round seeds Ss - heterozygote with round seeds ss - homozygote with wrinkled seeds
1. <span>A Pea plant that is homozygous for inflated pods are heterozygous for round seeds: PPSs 2. A</span><span> plant that is heterozygous for inflated pods and a homozygous for wrinkled seeds: Ppss
Let's look at their genotypes separately, and cross them that way:
Parents: PP x Pp Offspring: PP PP Pp Pp All of the offspring will have the same phenotype (100% = 1). So, this trait does not affect phenotypic ratio
</span>Parents: Ss x ss Offspring: Ss Ss ss ss Half of the offspring will have wrinkled seeds and half of them will have round seeds: 50% : 50% = 1 : 1
<span>Winds are caused by air moving around in the atmosphere. Wind turbines harness the mechanical energy in wind and convert it into electricity. Solar energy is the source of the mechanical energy in wind. </span>
