Explanation:
In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus
<u>Answer</u>: C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.
<u>Explanation</u>: In a diploid organism as the pea plant, a single gene has two alleles or versions, one on each chromosome. Each of these alleles can either be dominant or recessive.
Dominant alleles, such as that producing a yellow pod, will mask the contribution to the phenotype of the second allele, which is recessive. Here, the yellow pod allele will mask the contribution of the green pod allele. Thus, the offspring will have the phenotype (pod color) yellow.
However, both alleles for pod color will be present in the offspring as each parent will provide one chromosome during sexual reproduction.
Answer:
The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.
Explanation:
<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>
This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies of occurring together and decreasing the frequency of their recombination.
Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.
Answer:Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals. ... In sexual reproduction in animals, the two gametes are the spermatozoa and the oocyte, which when fused become the ovum.
