Answer:
d. in the presence of lysozyme, as found in tears, the proteins form aprotective barrier on the lens.
Answer:
Option C, zygote
Explanation:
The complete question is
The cell produced by the fusion of an egg and a sperm is the
a. gamete
b. oocyte
c. zygote
d. germ line cells
e. somatic cell
Solution
During the process of fertilization in sexual reproduction, when a male gamete (sperm) and female gamete (egg) fuses they form a new cell known as zygote.
Both male and female gamete are haploid with”n” number of chromosomes (only a single set of genes) and when they combine they form diploid zygote with “2n” number of chromosomes.
Hence, option C is correct
The best way to know the probabilities here is to do each cross and see the results.
a. Aa Bb Cc Ddx aa bb cc dd
Aa Bb Cc Dd
Aa Bb Cc Dd
aa bb cc dd
aa bb cc dd
You have 50% chances of Aa Bb Cc Dd which is phenotypically the same as one of the parents, and 50% chances of aa bb cc dd which are phenotypically the same as one of the parents.
b. aa bb cc dd x AA BB CC DD
aA bB cC dD
aA bB cC dD
aA bB cC dD
aA bB cC dD
You have 100% chances of having aA bB cC dD offspring, and it will be phenotypically the same as the AA BB CC DD because of the dominant allele.
c. Aa Bb cc Ddx Aa Bb cc Dd
AA BB cc DD
Aa Bb cc Dd
aA bB cc dD
aa bb cc dd
You have 25% chances of AA BB cc DD, 50% chances of Aa Bb cc Dd which are phenotypically the same as both the parents and 25% chances of aa bb cc dd.
d. aa bb cc dd x aa bb cc dd
aa bb cc dd
aa bb cc dd
aa bb cc dd
aa bb cc dd
You have 100% chances of having aa bb cc dd which are phenotypically the same as both the parents.
