Answer:
it says that plants are the main source of nutrients and energetic materials and when the cow feed on them, it consumes some of the benefits that we miss when we eat beef
<span>The role of the pollen is for the sperm to reach the egg. In the process of transportation, a lot of pollen grains can get lost and therefore there is greater need for it to be more than the ovules, since the eggs do not have to be transported anywhere. </span>
If a homozygous short plant (tt) is crossed with a heterozygous tall plant (Tt), the percentage of tall offsprings is 50% and the percentage of short offspring is 50%.
- A heterozygous tall pea plant will have the genotype "Tt" and a homozygous short pea plant will have the genotype "tt" because homozygous means that both alleles are identical.
- Since 'T' is dominant over 't', any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.
- The punett square of the following problem will have 2 squares with Tt genotype and 2 squares with tt genotype.
Hence, the genotypic ratio of F1 generation will be
Tt : tt
1 : 1
And phenotypic ratio of F1 generation will be
Tall : Short
1 : 1
