a)
lack of his ability to communicate
b)
his deafness
c)
lack of the availability of efficient communication methods
d)
him being held captive in jail
Sushil Kumar answered • 1 hour agoMendel had published his work back in 1865. The communication methods were not well developed and for people to recognize the importance of his work took more than half a decade after it had been published.

d)
Emasculation
Learners Habitat answered • 1 hour agoPeople had performed crosses on garden pea plants before Mendel. But no one had applied a statistical and probabilistic approach to unveil the underlying phenomena. Mendel was the first to do so.
Which of the following was not observed in F2 progeny of true-breeding tall and dwarf plants?- a)Homozygous tall plants

Which of the following was not observed in F2 progeny of true-breeding tall and dwarf plants?
a)
Homozygous tall plants
b)
Heterozygous tall plants
c)
Homozygous dwarf plants
d)
Heterozygous dwarf plants
Shiksha Academy answered • 1 hour agoThe F2 progeny has both dwarf and tall plants. 25% of them are homozygous tall, 50% are heterozygous tall, and 25% are homozygous dwarf. Dwarfness is a recessive trait and thus cannot be expressed in the heterozygous state.

During meiosis, what happens to the parental alleles?
a)
They segregate
b)
They undergo repair
c)
They undergo breakage
d)
They replicate
Mohit Rajpoot answered • 1 hour agoBased on his studies on pea plants, he observed that the parental recessive traits were observed again only in the F2 progeny without any form of blending in F1 generation. This points out that the factors segregate or separate during the process of meiosis.

With green pods as a dominant trait over yellow, which of the following crosses will result in all progeny having yellow pods?- a)Homozygous green and homozygous yellow
- b)Heterozygous green and heterozygous green
- c)Homozygous yellow and homozygous yellow

Correct answer is option 'C'. Can you explain this answer?
With green pods as a dominant trait over yellow, which of the following crosses will result in all progeny having yellow pods?
a)
Homozygous green and homozygous yellow
b)
Heterozygous green and heterozygous green
c)
Homozygous yellow and homozygous yellow
d)
Homozygous green and homozygous green
Bs Academy answered • 1 hour agoYellow being recessive will express only when both alleles are present. That occurs only when both parents can contribute an allele encoding for the yellow pod. For all progeny to have yellow pods, both parents have to be homozygous for yellow pods.
