Summary. Enzymes are catalysts that, within the mild conditions of temperature, pH, and pressure of the cells, carry out chemical reactions at amazing high rate. They are characterized by a remarkable efficiency and specificity. Substrates are the substances on which enzymes act.
1) autosomal dominant
2) autosomal recessive
3) X-linked dominant
4) X-linked recessive
Answer:
<u>Part A</u> : 70 secondary oocytes will be formed.
<u>Part B</u> : 70 first polar bodies will be formed.
<u>Part C</u> : 70 ootids will be formed.
Explanation:
During oogenesis growth maturation of a single oogonium produces one primary oogonium.
the primary oogonium then undergoes meiosis -1 and produces one secondary oocyte and first polar body.
The secondary oocyte then undergoes meiosis - 2 and forms an ootid and second polar body.
The ootid then differentiates into the ovum.
As in the above scenario , 70 primary oocytes are present , they undergo meiosis-1 and produces 70 secondary oocytes and 70 first polar bodies. Hence answers of part A and B is 70.
As 70 secondary oocytes are formed , they undergo meiosis -2 and forms 70 ootids which then differentiate in 70 ovums.
Answer:
The correct answer is C.
Explanation:
In the question, it is stated that the woman is heterozygous, which means she posseses both the dominant allele and the recessive allele (A and a). So taking this information into account, she can produce eggs given with the option C (Aa) which include both the dominant and recessive alleles.
I hope this answer helps.
